A rheostat changes the effective resistance in a circuit by moving a sliding contact along a resistive element. When connected correctly, changing the effective resistance changes the current for a given supply voltage, in accordance with Ohm’s law.
Ohm’s Law: V = I × RHere, V represents voltage, I represents current and R represents resistance. Actual circuit values depend on the connected components and the instrument's operating limits.
Applications in Physics Laboratories
Demonstration of variable resistance in an electrical circuit.Study of current variation with resistance.Educational demonstrations of Ohm’s law.Basic electrical practicals in school and college laboratories.General Experimental Procedure
- Ensure the power supply is switched off before making connections.
- Connect the rheostat to the circuit according to the experiment instructions and the manufacturer's guidance.
- Set the sliding contact to the recommended starting position.
- Switch on the supply only after checking the circuit connections and ratings.
- Adjust the resistance gradually and observe the change in current using a suitable meter.
- Switch off the supply before changing the wiring or handling the apparatus.
Do not exceed the specified current rating. Follow the manufacturer's instructions and the laboratory supervisor's safety guidance.
