About This Product
In an Ohm's law practical the rheostat is wired into the circuit with the supply off and the slider set to a safe starting point. Once the low-voltage supply is on, students move the slider gradually and note the ammeter and voltmeter readings at each position. It is not meant for mains voltage or for use beyond its labelled rating.
Frequently Asked Questions
Q1. How does the rheostat change the current?
Sliding the contact along the resistance changes how much resistance is in the circuit. More resistance lowers the current and less resistance raises it, which students read on an ammeter.
