What Is the Moving Coil Galvanometer Used For?
Because the pointer rests at the centre, the meter shows both the presence and the direction of a small current. As a galvanometer for school laboratories, its main job is null detection in meter bridge, Wheatstone bridge and potentiometer practicals: students move the jockey until the pointer returns to zero, then read the balancing length.
It is also used to demonstrate electromagnetic induction, where pushing a magnet into a coil and pulling it out swings the pointer first one way and then the other. Tap the jockey briefly rather than holding it down, and add a high resistance in series for the first trials so the pointer stays on scale.
What to Specify When Ordering
- Confirm that the 30-0-30 scale and the listed 200 microampere sensitivity suit your experiments.
- Quantity required, usually one per bridge or potentiometer set.
- Whether resistance boxes, jockeys or plug keys should be quoted with it.
Supplier
Jain Scientific Equipments Private Limited trades as ScienceLab and supplies this moving coil galvanometer from Ambala, Haryana, to schools, colleges, institutions and dealers in India and international markets. The company sources it for customers who want galvanometers, bridges and resistance boxes from a single supplier, so one quotation can cover the whole electricity bench. Company background is on the ScienceLab profile.
Related Physics Lab Equipment
A galvanometer is rarely used on its own. These items complete typical null-detection circuits:

Ebonite Rod
Ebonite Rod (Product Code: SCL-363/080) is a round black ebonite rod used to produce static charge by friction in school and college physics laboratories. Rubbed with fur or wool, it picks up a negative charge, which makes it a standard partner for electroscopes in electrostatics demonstrations; rods are offered in different diameters. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.
Key Details
| Parameter | Detail |
|---|---|
| Material | Ebonite |
| Shape | Round |
| Colour | Black |
| Diameters | Different diameters available |
| Product code | SCL-363/080 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is the Ebonite Rod Used For?
Ebonite is a hard vulcanised rubber and a good insulator, so charge produced on its surface by rubbing stays there long enough to be studied. Students rub the rod with fur or wool and bring it near small pieces of paper, a suspended pith ball or the disc of a gold leaf electroscope to show attraction, repulsion and charging by contact or induction.
Pairing it with a glass rod rubbed with silk shows that two kinds of charge exist, because the two charged rods attract each other. Electrostatic experiments work best in dry air, so wipe the rod clean and dry before use and avoid touching the rubbed end. It is basic physics lab equipment for electrostatics lessons in schools across India.
What to Specify When Ordering
- The diameter you need, since rods are offered in different diameters.
- The length required, as it is not stated in the listing.
- Quantity, and whether rubbing cloths or an electroscope should be quoted with it.
Supplier
Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies ebonite rods from its base in Ambala, Haryana, to schools, colleges, institutions and dealers in India and international markets. Ordering the rod together with electroscopes and other electrostatics items means one supplier and one quotation for the whole set. Find out more on the company profile.
Related Physics Lab Equipment
Electrostatics lessons combine charging rods, rubbing materials and a detector. Items used alongside the ebonite rod:
- Gold Leaf Electroscope — detects and compares the charge on the rod.
- Friction Rod, Glass/Brass, 300mm — a glass rod for producing the opposite charge.
- Friction Cloth, Cotton — a cloth for rubbing charging rods.
- Friction Rod, Perspex — another insulating rod for comparing charging behaviour.
See other electrostatics apparatus in the Physics Lab category.
Frequently Asked Questions
What is the Ebonite Rod made of?
The Ebonite Rod is made of ebonite, a hard black vulcanised rubber, and is round in shape. Ebonite is a good electrical insulator, which is why the rod holds the charge produced on it by rubbing during electrostatics experiments.
What charge does an Ebonite Rod acquire when rubbed?
An Ebonite Rod rubbed with fur or wool becomes negatively charged, because electrons transfer from the fur to the ebonite. A glass rod rubbed with silk becomes positively charged, so the two are used together to show like and unlike charges.
Which diameters of Ebonite Rod are available?
The Ebonite Rod is offered in different diameters, but the listing does not give specific sizes or lengths. Tell us the diameter and length you prefer through the contact page, and we will confirm what can be supplied with your quotation.

| Measures | Potential difference (voltage) between two points in an electrical or electronic circuit |
| Range | 0–15 V |
| Current type | DC |
| Typical users | School, college, university and research laboratories |
| Product code | SCL-369/083 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is a Voltmeter Used For?
A voltmeter reads the potential difference across a resistor, a cell or any other component, so it is the partner to the ammeter in almost every electricity practical. In the Ohm’s law experiment, for example, students read the voltage across the resistance wire for several rheostat settings and plot it against current to find the resistance.
Always connect the meter in parallel with the component, with its positive terminal towards the higher-potential side, and check that the circuit supply stays within the 0–15 V DC range. Choosing a supply that places readings in the upper part of the scale improves reading accuracy, and noting the scale’s least count before starting helps students record values correctly.
What to Specify When Ordering
- That a 0–15 V DC range suits the circuits in your practical syllabus.
- The number of voltmeters required, usually one per workbench.
- Whether you also need a matching ammeter, rheostat and connecting leads.
OEM Manufacturer
The Voltmeter is manufactured by Jain Scientific Equipments Private Limited, which trades as ScienceLab, acting as the original equipment manufacturer (OEM). It is made at the company’s own licensed factory at Saha, Ambala, Haryana, and supplied factory-direct to schools, colleges, universities, dealers and importers rather than through a trader. ScienceLab is a registered MSME (Udyam UDYAM-HR-01-0003714), and export orders are shipped under Importer-Exporter Code AAECJ8618A issued by the DGFT. Read more on the company profile.

Frequently Asked Questions
What range does the Voltmeter measure?
The Voltmeter measures DC voltage from 0 to 15 V. That range covers the low-voltage circuits built from cells or a lab DC supply in school and college practicals, such as Ohm’s law, cell and resistance experiments.
How is the Voltmeter connected in a circuit?
The Voltmeter is always connected in parallel, across the component whose potential difference you want to read, with its positive terminal on the higher-potential side. Connecting it in series with the rest of the circuit would block the current and give a misleading reading.
Can the Voltmeter measure AC voltage?
No, the Voltmeter is listed as a DC instrument with a 0 to 15 V range, so it is intended for direct-current circuits only. For alternating-current measurements, ask us through the contact page which meter would suit your experiment before ordering.
Who manufactures the Voltmeter?
The Voltmeter is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own factory at Saha, Ambala, Haryana, India. Orders, spare-part questions and repeat supplies are handled by the manufacturer itself, without a trader in between.
Is a calibration certificate available with the Voltmeter?

Ammeter
Ammeter (Product Code: SCL-371/084) is a moving-coil DC ammeter with a 0–5 A range used to measure the current flowing in circuits during school and college physics practicals. It stands on a square-based desk stand with lock-type terminals and is specified to an accuracy of ±2.0% of full-scale deflection. The Ammeter is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.
Specifications
| Parameter | Detail |
|---|---|
| Movement | Moving coil |
| Current type | DC |
| Range | 0–5 A |
| Accuracy | ±2.0% of full-scale deflection (F.S.D.) |
| Terminals | Lock-type terminals |
| Mounting | Desk stand on a square-shaped base |
| Product code | SCL-371/084 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is a Moving Coil Ammeter Used For?
The ammeter is placed in series in a circuit so that the whole current passes through it, which makes it essential for Ohm’s law, series and parallel resistance and rheostat current-control experiments. Its 0–5 A range handles the larger currents drawn by low-resistance circuits, while a milliammeter is the better choice for very small currents.
As a staple of physics lab equipment for schools in India, it should be wired with its positive terminal towards the positive side of the supply and never connected straight across a cell. Because the ±2.0% accuracy is quoted on full scale, readings in the upper part of the dial are proportionally more precise, so adjust the rheostat to bring the needle well up the scale.
What to Specify When Ordering
- That a 0–5 A DC range suits your experiments, or whether a milliammeter is also needed.
- The number of ammeters required for your workbenches.
- Any matching voltmeters, rheostats, keys or leads to include in the same quotation.
OEM Manufacturer
ScienceLab is the brand of Jain Scientific Equipments Private Limited, and this Ammeter is one of the meters the company builds itself, as OEM, at its factory in Saha, Ambala, Haryana, India. Meters leave the factory directly for schools, colleges, dealers and importers, so questions about replacement parts or repeat batches go straight to the maker — just ask us. Company details are on the ScienceLab profile.
Related Physics Lab Equipment
Apparatus normally wired into the same circuit as the ammeter:
- Voltmeter — reads the potential difference while the ammeter reads current.
- Milliammeter — a lower-range meter for currents in milliamperes.
- Rheostat 30 Ohm — adjusts the circuit current to bring readings up the scale.
- One Way Key — switches the circuit on only while readings are taken.
- Resistance Box — provides known resistances for current measurements.
The Physics Lab category lists the remaining meters and circuit apparatus.
Frequently Asked Questions
What are the range and accuracy of the Ammeter?
The Ammeter reads DC current from 0 to 5 A with a stated accuracy of ±2.0% of full-scale deflection (F.S.D.). Because the error is quoted on the full scale, readings taken in the upper part of the scale are relatively more precise than readings near zero.
How should the Ammeter be connected in a circuit?
The Ammeter must be connected in series so that the whole circuit current passes through it, with its positive terminal towards the positive side of the supply. Never connect it directly across a cell or power supply, as the meter’s very low resistance would allow a damaging current.
What type of movement does the Ammeter use?
The Ammeter uses a moving-coil movement designed for direct current, so the needle deflects in proportion to the current flowing through the coil. Moving-coil meters respond to DC only, which is why the Ammeter should not be connected to an AC supply.
How is the Ammeter mounted on the bench?
The Ammeter comes on a desk stand with a square-shaped base and lock-type terminals. The stand keeps the meter steady and upright on the workbench, and the lock-type terminals hold connecting wires or leads securely while students take their readings.
Who manufactures the Ammeter?
The Ammeter is manufactured by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, as the OEM at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct, so quotations and follow-up questions are handled by the manufacturer rather than a trader.
Can the Ammeter be ordered for a whole laboratory?
Yes, the Ammeter can be ordered in bulk for school and college laboratories, dealers and tender supplies in India and international markets. Share the quantity, the delivery location and any matching voltmeters or rheostats, and the manufacturer will quote for the complete set.

What Is a Milliammeter Used For?
A milliammeter reads currents that are too small to show clearly on an ampere-range meter, such as the current through an LED, a semiconductor diode or a high resistance. In school and college practicals it is wired in series with the component, so students can see how the current changes as they vary the supply or the resistance.
Before each session, set the needle to zero with the zero adjustment, then match the colour-coded binding posts to the polarity of the supply. Include a series resistance when building a new circuit so the current stays within 500 mA, and increase the supply gradually while watching the needle.
What to Specify When Ordering
- That a 0–500 mA DC range suits your experiments, or whether a 0–5 A ammeter is also needed.
- The number of meters needed for your workbenches.
- Any leads, resistance boxes or components to be quoted alongside.

Frequently Asked Questions
What range does the Milliammeter cover?
The Milliammeter covers 0 to 500 mA DC. It is intended for small circuit currents, such as those through LEDs, diodes or high resistances, where an ampere-range meter would show only a small movement of the needle.
How accurate is the Milliammeter?
The Milliammeter is listed with an accuracy of ±2.5%. For the most reliable values, set the needle to zero with the zero adjustment before use and choose circuit values that bring the reading well up the scale rather than near zero.
Does the Milliammeter have a zero adjustment?
Yes, the Milliammeter features a zero adjustment, so the needle can be reset to zero before a practical begins. Checking zero at the start of each session removes a common source of error when students record small currents.
What is the Milliammeter housing made of?
The Milliammeter is fully enclosed within a sturdy plastic housing and has colour-coded binding posts. The closed case protects the movement from dust and handling, and the colour coding helps students connect the meter with the correct polarity.
Who supplies the Milliammeter?
The Milliammeter is supplied by Jain Scientific Equipments Pvt Ltd, which trades as ScienceLab and is based in Ambala, Haryana, India. It is offered to schools, colleges, dealers and importers across India and international markets with other physics lab apparatus.
