Simple Circuit Module Light Dependent Resistor Board (Product Code: SLE/PHY/79) is a board-mounted light dependent resistor from the Simple Circuit Modules range, used to add a light sensor to school electricity circuits. In normal room conditions its resistance is approximately 250 ohms, and shading it raises the resistance, so students can watch light level control a circuit. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the LDR Circuit Module Used For?

Placed in series with a lamp or LED module and a few cells, the LDR board makes the light output change as students cover and uncover it, a direct way to show that resistance controls current. With a multimeter across it, groups can record resistance against the distance from a lamp and plot a graph, a common activity in OPTO electronics experiment kit lessons.

Because the resistor is already mounted, there are no fragile leads to bend and the module drops into a circuit alongside the other boards in the range. Take readings away from direct sunlight so results repeat from one group to the next, and compare the board with the bare component when explaining how sensors are built into real products.

What to Specify When Ordering

• Number of LDR boards needed
• Other Simple Circuit Modules to go with them, such as LED, lamp or switch boards
• Whether you need the fully covered resistance value confirmed before ordering

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies this LDR board with the other boards in its Simple Circuit Modules range, so a school can assemble a matched set in one order. Institutions completing vendor forms can use the company's GSTIN 06AAECJ8618A1ZT and its Legal Entity Identifier 3358004HRD1JIVXKYX49. More about the company is on the ScienceLab profile.

Jockey with Insulated Handle (Single) (Product Code: SLE/PHY/80) is a hand-held contact probe used to find the balance point on the wire of a Wheatstone bridge or potentiometer in physics practicals. It is 100 mm long overall, with an insulated handle, a plated brass contact and a 4 mm plug terminal for connection to the circuit. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Insulated Jockey Used For?

In bridge and potentiometer experiments the jockey is the moving contact: the student touches it onto the resistance wire at different points until the galvanometer shows no deflection, then reads the balancing length from the scale. The 4 mm plug terminal pushes into a lead or socket, so the jockey links the wire to the galvanometer without a loose clip.

The insulated handle keeps fingers off the circuit and stops hand contact from disturbing the reading, which matters in any meter bridge lab in India where many students share the same apparatus. Tap the brass contact gently and lift it between trials rather than sliding it, since a dragged contact scores the wire. Wipe the tip clean if readings start to jump.

What to Specify When Ordering

• Number of jockeys (this listing is for a single jockey)
• The bridges or potentiometers they will be used with, if you also need those quoted
• Whether you prefer this plug-terminal jockey or a pencil (knife-edge) type

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the original equipment manufacturer of this jockey. It is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, the same factory that makes the bridges and potentiometers it is used with, so labs can match jockeys to their apparatus through one manufacturer. Schools, dealers and importers order factory-direct, and repeat orders for spares are handled by the maker itself. See the company profile for more.

Potentiometer Module, 1 Kohm (Product Code: SLE/PHY/81) is a 1 kΩ rotary linear potentiometer mounted on a channel box, used as a variable resistor or adjustable voltage divider in school electricity and electronics circuits. Connections are made through 4 mm sockets, and a fast-blow fuse protects the module when students connect it wrongly. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to physics labs and dealers.

Specifications

What Is the Potentiometer Module Used For?

Wired with two of its sockets, the module acts as a variable resistor that dims a lamp or LED as the knob turns. Using all three sockets across a low-voltage supply, it becomes a voltage divider that gives a smoothly adjustable output, which students can measure with a voltmeter while they vary the load in Ohm law experiment kit set-ups.

Because the track is linear, equal turns of the knob give roughly equal changes in resistance, so students can relate knob position to the reading they see. If the module stops working after a wiring mistake, check the fast-blow fuse first. Keep supply voltages low and switch off before changing connections.

What to Specify When Ordering

• Resistance value — 1 kΩ for this listing, or another value from the range
• Number of modules for the class
• Spare fuses, and the fuse rating to be confirmed with us
• Leads with 4 mm plugs if your lab does not already have them

Supplier

This potentiometer module is supplied by Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, as part of its range of plug-in circuit modules and physics instruments for schools and colleges.

• Potentiometer Module — the same module family, for other resistance values
• Simple Circuit Module LED Board Green — an LED load to dim with the module
• Standard Digital Multimeter — to measure the divider output and current
• Power Supply Variable — a low-voltage source for divider circuits
• Stackable Leads — leads for connecting the module into a circuit

More options are listed under Physics Lab Equipment.

Frequently Asked Questions

What resistance does the Potentiometer Module have?
The Potentiometer Module, 1 Kohm has a 1 kΩ rotary linear potentiometer. The module is offered in a choice of values, so state the resistance you need when ordering if another value suits your experiments better.

What does the fuse in the Potentiometer Module do?
The Potentiometer Module, 1 Kohm includes a fast-blow fuse that protects it when students connect it wrongly, for example directly across a supply. If the module stops responding, check and replace the fuse before assuming the potentiometer has failed.

How is the Potentiometer Module connected?
The Potentiometer Module, 1 Kohm connects through 4 mm sockets on its channel box. Use two sockets to wire it as a variable resistor, or all three across a supply to use it as an adjustable voltage divider.

What does linear mean for this potentiometer?
On the Potentiometer Module, 1 Kohm, linear means the resistance changes in proportion to how far the knob is turned. Students therefore see an even change in current or voltage as they rotate it, which makes readings easier to interpret.

Who supplies the Potentiometer Module, 1 Kohm?
The Potentiometer Module, 1 Kohm is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges and dealers in India and international markets, alongside meters and other circuit modules.

Student Microscope with Movable Condenser (Product Code: SLE/M/18) is a student compound microscope whose condenser can be moved, used to teach slide observation and light control in school and college biology laboratories. Adjusting the condenser lets students see for themselves how the light reaching a specimen changes brightness and contrast, a step beyond fixed-condenser class models. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India; please ask us for its current specification before ordering.

Key Details

What Is the Movable-Condenser Student Microscope Used For?

A student microscope of this kind is used for routine slide practicals, such as plant cells, cheek cells, leaf sections and prepared slides, in classes that also want students to learn correct illumination. The condenser gathers light from the source below the stage and focuses it on the specimen; being able to move it lets the user match that light to the objective in use.

A simple routine works well: focus the specimen at low power, then move the condenser until the field is evenly and comfortably lit. Bring it close to the slide when switching to high power, where more light is needed, and move it away for low-power or unstained mounts, where softer light often shows more detail. Teachers can pair it with the fixed-condenser model so students compare the two set-ups side by side.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, supplies this movable-condenser student microscope to schools, colleges, dealers and importers in India and international markets. Because the detailed specification is confirmed at quotation stage, our team will set out the optics, stage and lighting in writing so you can check them against your syllabus or tender.

LED, 5 mm, White (Product Code: SLE/PHY/82) is a standard 5 mm white light-emitting diode used as a light source and indicator in school electronics circuits, science projects and physics practicals. It comes in a pack of 100, enough to equip a whole class, and the same 5 mm LED is available in a range of colours. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the 5 mm White LED Used For?

White LEDs give a clear, bright light, which makes them the natural choice when an experiment needs illumination rather than just an on/off signal. Students use them to light model houses and torches, to shine on a light dependent resistor in sensor experiments, and to compare the light and current of an LED with a filament bulb in LED characteristics experiment kit work.

A pack of 100 also covers science fair project kit needs in India's schools, where many pupils build lit displays at the same time. Always connect a suitable series resistor, observe polarity (the longer lead is usually the anode), and store the LEDs in their pack so the leads do not tangle or bend.

What to Specify When Ordering

• Number of packs of 100
• Any other colours from the 5 mm range, such as bright red or blue
• Whether you prefer board-mounted LED modules with a built-in resistor for younger classes

Simple Circuit Module LED Board Green (Product Code: SLE/PHY/84) is a board-mounted green light-emitting diode from the Simple Circuit Modules range, used as an indicator lamp in school electricity circuits. It carries a large LED with a series resistor of 220 ohms, so it can be used on potential differences of up to 6 V without adding a separate resistor. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Green LED Circuit Module Used For?

Younger students can drop the green LED board straight into a circuit with a few cells, because the 220 ohm resistor already limits the current. Connected one way it glows, and turned round it stays dark, which makes it a clear first demonstration of how a diode conducts in only one direction and a good starting point for LED characteristics experiment kit lessons.

Used alongside the red LED board, it shows which way current flows in a circuit or forms the "go" light in a traffic-light model. Keep the supply at 6 V or below, as listed, and add it to other boards in the range, such as a switch or light dependent resistor module, to build sensor and control circuits for an electricity experiment kit at school level.

What to Specify When Ordering

• Number of green LED boards
• Whether matching red LED boards are needed for polarity or traffic-light work
• Other Simple Circuit Modules, such as switch, buzzer or LDR boards, for complete circuits

Supplier

The green LED board is supplied by Jain Scientific Equipments Private Limited, trading as ScienceLab, as part of the Simple Circuit Modules range it offers to schools and dealers from Ambala, Haryana. Buyers can build a full module set from one quotation. Read more on the ScienceLab company profile.

Explore more in Physics Lab Equipment.

Frequently Asked Questions

What resistor is fitted on the LED Board Green?
The Simple Circuit Module LED Board Green has a 220 ohm series resistor with its large green LED. The resistor limits the current, so the board can be connected to classroom supplies without students having to choose and fit a resistor themselves.

What is the maximum voltage for the green LED board?
The Simple Circuit Module LED Board Green is listed for potential differences of up to 6 V. Keep the supply at or below this level, for example a small group of cells, so the LED and its 220 ohm resistor are not overloaded.

Why does the green LED board not light when connected?
If the Simple Circuit Module LED Board Green stays dark, it is most likely connected the wrong way round, because an LED conducts in one direction only. Reverse the connections, then check the cells and leads if it still does not light.

How is the LED board different from a loose LED?
The Simple Circuit Module LED Board Green carries a large LED with its 220 ohm resistor already fitted on a board, ready for module circuits. A loose 5 mm LED needs a separate resistor and suits soldered or breadboard projects instead.

Who supplies the Simple Circuit Module LED Board Green?
