Rheostat 8 Inch 100 Ohm 1.6A

The 100 Ohm rheostat 1.6A is an 8-inch variable-resistance apparatus used for controlling resistance and current in electrical circuits during physics laboratory experiments. Designed for school and college physics laboratories, it enables students and instructors to vary circuit resistance while studying current, voltage, resistance, and Ohm’s law.

Product Description

The STEMAids Rheostat 8 Inch 100 Ohm 1.6A is a laboratory variable resistor with a stated resistance capacity of 100 Ω and current rating of 1.6 A. Its adjustable resistance makes it suitable for circuit experiments where the electrical resistance must be changed progressively while observing corresponding changes in current or voltage.

The product is intended for hands-on electricity experiments, circuit demonstrations, practical physics lessons, and laboratory investigations. The exact resistance-wire material, former material, terminal construction, overall dimensions beyond the stated 8-inch size, and weight have not been verified for this specific model and therefore are not stated here.

Key Features

• 100 Ω resistance capacity: Provides variable resistance up to the stated 100-ohm rating for laboratory circuit work.
• 1.6 A current rating: Suitable for experiments operated within the specified electrical rating.
• 8-inch nominal size: Identified as an 8-inch rheostat for laboratory and educational use.

How to Use the Rheostat 8 Inch 100 Ohm 1.6A

1. Switch off the circuit power before making or changing connections.
2. Connect the rheostat into the experimental circuit according to the required circuit diagram.
3. Set the adjustable contact to a suitable starting position before energising the circuit.
4. Switch on the power supply and observe the connected ammeter, voltmeter, or other measuring instrument.
5. Adjust the rheostat gradually to vary resistance and record the corresponding electrical measurements.
6. Switch off the circuit before disconnecting or rearranging components.

Safety note: Operate the rheostat within its stated 1.6 A rating. Avoid touching conductive connections while a circuit is energised, and use the apparatus under appropriate laboratory supervision.

Care & Maintenance

• Keep the rheostat dry and store it away from corrosive chemicals and excessive moisture.
• Move the adjustable contact smoothly rather than forcing the mechanism.
• Inspect terminals and connecting points before laboratory use.
• Disconnect the apparatus from the circuit before cleaning or storage.
