The physics lab sliding rheostat is a variable-resistance apparatus used for adjusting resistance and controlling current in electrical circuits. It is intended for supervised school, college and technical laboratory experiments where students need to observe how changing resistance affects current, voltage and overall circuit behaviour.
Product Description
The STEMAids Physics Lab Sliding Rheostat provides manually adjustable electrical resistance for practical circuit investigations. A movable sliding contact allows the effective resistance in a suitable circuit to be varied progressively, making the apparatus useful for demonstrations and measurements involving current, voltage and resistance.
The sliding rheostat is designed for hands-on physics laboratory work and instructor-led electrical experiments. The resistance range, current rating, resistance-wire material, dimensions, weight and construction materials for this exact model have not been published in verified product information and should be confirmed before specification-sensitive procurement.
Key Features
- Variable resistance: Enables progressive adjustment of resistance in compatible laboratory circuits.
- Sliding adjustment: Uses a movable contact to change the effective resistance during an experiment.
- Current-control applications: Helps demonstrate how increased or decreased resistance changes circuit current.
- Physics practical use: Suitable for supervised electricity and circuit experiments in educational laboratories.
- Hands-on learning: Allows students to observe electrical relationships rather than study them only theoretically.
- Reusable apparatus: Can support repeated classroom demonstrations and practical sessions when correctly handled.
- Compatible with circuit measurements: Can be incorporated into suitable setups using laboratory meters, power sources and electrical components.

Frequently Asked Questions
What is a sliding rheostat used for in a physics lab?
A sliding rheostat is used to vary electrical resistance in a circuit. This allows students to investigate how resistance influences current and voltage.
How does a sliding rheostat work?
A sliding rheostat changes the effective resistance when its movable contact is repositioned along the resistance element. The resulting resistance change can be observed through corresponding circuit measurements.
Can this rheostat be used for Ohm’s law experiments?
Yes. A sliding rheostat can form part of an appropriate Ohm’s law setup with a compatible power supply, ammeter, voltmeter and test resistor.
Is the Physics Lab Sliding Rheostat suitable for schools?
Yes. It is suitable for supervised educational experiments involving variable resistance, current control and basic circuit behaviour in school and college physics laboratories.
What is the resistance range of this sliding rheostat?
The resistance range for this exact STEMAids model has not been verified. Buyers should confirm the required resistance and current ratings before ordering for a specified experiment or tender.
What material is this rheostat made from?
The resistance-wire and structural materials for this exact model have not been verified. They are therefore intentionally not specified here.
