Simple Circuit Module Motor (Product Code: SLE/PHY/69) is a low-voltage d.c. motor mounted on a base, used to show electrical energy turning into movement in simple circuit experiments at school. A series resistor is fitted to limit the motor’s current consumption, and the module belongs to the same Simple Circuit Modules range as the LED boards, so it combines with other modules in electricity experiment kits for schools. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Is the Simple Circuit Module Motor Used For?

A spinning motor is one of the most convincing ways to show that a circuit is complete. Students can compare the motor with a lamp or LED board as different “outputs”, add a switch module to control it, or reverse the supply connections to see the direction of rotation change — a quick introduction to how d.c. motors respond to polarity.

The fitted series resistor keeps current draw modest, which helps cells last through a lesson of beginners’ circuit building. A small paper flag or disc fixed to the shaft makes slow rotation easier to see from the back of the room. Keep the base on a flat surface while running and let the motor stop before changing connections.

What to Specify When Ordering

• Number of motor modules needed for your groups.
• Other Simple Circuit Modules to match, such as LED boards, push switch or LDR board.
• Whether you need a supply voltage recommendation for the module — ask us when enquiring.

Light Dependent Resistor (Product Code: SLE/PHY/71) is a cadmium sulphide (CdS) photoconductive cell used to sense light levels in school electronics circuits, physics practicals and student projects. Its resistance falls as more light reaches it, from a dark resistance of 1 MΩ, and its spectral response is similar to that of the human eye. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a component for school physics lab equipment in India and international markets.

Specifications

What Is a Light Dependent Resistor Used For?

In class, the LDR is usually wired in series with a fixed resistor to form a voltage divider, so the output voltage changes with light level. That simple arrangement is the basis of automatic night lights, light meters and burglar-alarm circuits that students build in electronics lessons. It is a standard part in OPTO electronics experiment kit work alongside LEDs and phototransistors.

For a quick demonstration, connect the LDR to a multimeter on its resistance range and let students cover it, uncover it and move a lamp closer while they note the readings. Because its response is similar to the human eye, results relate well to how bright a room looks. Bend the pins gently near the body, and keep power dissipation well under the 250 mW limit.

What to Specify When Ordering

• Quantity of LDRs needed for the class or project
• Whether you want the bare component or the board-mounted Simple Circuit Module version
• Any meters or light sources to be quoted with them

Potentiometer (Product Code: SLE/PHY/74) is a slide-wire potentiometer used to compare the emf of cells and measure potential differences by the null method in school and college physics laboratories. A 24 SWG constantan wire runs along a metre scale divided in cm and mm between stout plated brass end plates, and a jockey is included. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Slide-Wire Potentiometer Used For?

A steady driver cell connected across the wire sets up a uniform fall of potential along it. Students then use the jockey to find the balance point for a second cell or circuit, read the balancing length on the scale, and compare emfs, find the internal resistance of a cell or measure a small potential difference without drawing current at balance.

These experiments appear in most senior-secondary syllabi, which makes the potentiometer standard physics practical equipment for CBSE and state-board labs as well as first-year college courses. Press the jockey gently and lift it before moving along the wire; dragging it while pressed scratches the constantan and spoils the uniform resistance per centimetre. Keep the driver current low so the wire does not warm up during a reading.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this potentiometer. The company makes it at its own licensed factory at Saha, Ambala, Haryana, India, rather than buying it in from a trader, and supplies it factory-direct to schools, colleges, dealers and importers. Replacement jockeys and other spares are handled by the manufacturer itself — ask us when you order. More background is on the ScienceLab company profile.

Related Physics Lab Equipment

A complete potentiometer circuit needs a few more items on the bench:

• Jockey with Insulated Handle (Single) — a spare or replacement jockey
• Moving Coil Galvanometer — the null detector for finding the balance point
• Rheostat — to set the driver current through the wire
• One Way Key — to switch the driver circuit on only while reading
• Potentiometer, 10 wire — a longer-wire model for finer balance lengths

See more apparatus in Physics Lab Equipment.

Frequently Asked Questions

What is included with the Potentiometer?
The Potentiometer comes mounted on a polished hardwood baseboard with its 24 SWG constantan wire, metre scale, plated brass end plates and 4 mm socket terminals, and a jockey is included. Cells, galvanometer, rheostat and connecting leads are ordered separately.

What wire does the Potentiometer use?
The Potentiometer uses 24 SWG constantan wire stretched along a metre scale divided in centimetres and millimetres. Constantan is chosen because its resistance changes very little with temperature, giving a steady potential gradient along the wire during an experiment.

How large is the Potentiometer?
The Potentiometer measures approximately 1.13 m × 80 mm × 50 mm, so it needs a bench length of just over a metre. Leave space beside it for the driver cell, galvanometer, rheostat and key used in the circuit.

Who manufactures the Potentiometer?
The Potentiometer is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. Schools, dealers and importers receive quotations and repeat-order support directly from the manufacturer.

Is a calibration certificate available for the Potentiometer?
The Potentiometer works by the null method, with results taken from balance lengths on its scale. If your institution needs a calibration certificate or test report for it, please discuss the requirement with us through the contact page before ordering.

What should a quotation request for the Potentiometer include?
A quotation request for the Potentiometer should give the quantity, the delivery location, and whether you also need spare jockeys, galvanometers, rheostats or keys. With those details the manufacturer can quote a complete set for your physics lab in one reply.
