About This Product
The dual-tube construction suits practical training where this format is required. With all connections made and the supply off, the rheostat is set to the recommended safe starting position. Students then apply the low-voltage supply, move the slider gradually and record values from the ammeter and voltmeter to relate voltage, current and resistance. The Electrical Training Dual Tube Rheostat is available for supply within India and for export to Australia, Laos, Lebanon, Comoros and Central African Republic.
Frequently Asked Questions
Q1. What does the rheostat do in an Ohm's law experiment?
It varies the resistance in the circuit so that current can be changed in controlled steps while students record matching voltage and current readings.
