Potentiometer 100 Ohm Board

Product Code : SCL-EI-10648

The 100 Ohm Potentiometer Board is a variable-resistance electrical component manufactured and exported by Lab Glassware Manufacturer, based in Ambala, Haryana, India, in continuous operation since 1982. This board is supplied to school and college electronics laboratories across the Nordic region, including Sweden, Norway, Denmark, and Finland, supporting classroom demonstrations of variable resistance, voltage division, and current control.

Quick answer: The 100 Ohm Potentiometer Board is a variable resistor with a 100 ohm resistance value, used to demonstrate voltage division, current control, and brightness variation in low-voltage school circuits by turning a knob or shaft to adjust resistance between the end terminals or the wiper terminal. The exact body style, power rating, terminal type, and base construction should be confirmed with Lab Glassware Manufacturer before publication or tender submission.

Key Features

• 100 Ohm resistance value: suitable for basic resistance-variation and voltage-divider demonstrations.
• Physics and electronics use: supports hands-on circuit learning in school and college laboratories.
• Variable-resistance control: lets students observe how changing resistance affects current or voltage.
• Board/base format: suited to bench-top teaching use where the final mounting style is confirmed.
• Compatible with circuit apparatus: can be used with meters, lamps, cells, leads, and trainer boards where verified.
• Specification-dependent safety: current limit, insulation, and terminal design must be confirmed.

What's Included

• 1 x 100 Ohm Potentiometer Board / Base
• Terminals, knob, connection leads, label, instruction sheet, storage box, or certificate, only if specified in the order

Applications / Uses

• Demonstrating variable resistance in electrical circuits.
• Building simple voltage-divider circuits.
• Controlling current in low-voltage classroom circuits.
• Studying Ohm's law and resistance effects.
• Using with analogue meters, lamps, cells, and electronics trainer boards.
• Supporting school physics, STEM, and basic electronics practicals.

How to Use the 100 Ohm Potentiometer Board

1. Confirm the potentiometer power rating, voltage limit, terminal layout, and resistance value before use.
2. Inspect the knob, shaft, terminals, board, and connecting leads for damage.
3. Connect the potentiometer into the circuit according to the experiment diagram.
4. Use the two end terminals for full resistance, or the wiper terminal for variable output where marked.
5. Start with a low-voltage supply and rotate the control slowly.
6. Observe the change in meter reading, lamp brightness, or output voltage.
7. Do not exceed the confirmed current or power rating.
8. Disconnect the power supply after the experiment and store the board safely.

Safety note: Use only in low-voltage educational circuits unless the product is specifically rated otherwise. Do not connect the potentiometer directly across a high-current supply, mains power, or circuits exceeding the confirmed wattage.

Care & Maintenance

• Store the potentiometer board dry and away from dust, heat, and chemical vapours.
• Do not force the rotating shaft beyond its end stops.
• Keep terminals clean and tighten loose connectors before classroom use.
• Remove from service if overheating, burning smell, cracked insulation, or unstable readings occur.

Fixed vs. Variable Resistance Teaching Apparatus

The 100 Ohm Potentiometer Board adds a variable-resistance option to a resistance-teaching sequence built around fixed-value components. Schools already using the 50 Ohm Resistor Based Circuit Element or the Decade Resistance Box for fixed and stepped resistance values can add this potentiometer board to demonstrate continuously variable resistance and voltage division, and combine it with the Plug-in Board for Building Components for a complete bench-top circuit-building set.
