About This Product
With the supply off, the box is wired into the circuit and the required resistance arrangement is selected. Students then switch on the low-voltage supply, read the ammeter and voltmeter, and compare the measured current with the value predicted from Ohm's law. It is meant for supervised low-voltage work, not direct connection to mains. Besides buyers across India, the Physics Laboratory Resistance Box 100? can be exported to institutions in Latvia, Armenia, Maldives, Panama and Belgium.
Frequently Asked Questions
Q1. How is the box used to verify Ohm's law? With a known 100-ohm resistance in the circuit, students measure voltage and current, then check that voltage divided by current comes close to the stated resistance.
