Verified by Experts

We will require a voltmeter, an ammeter, a test resistor and a variable battery to verify Ohm’s law. Voltmeter which is made by connecting a high resistance with a galvanometer is connected in parallel with the test resistor. Further, an ammeter which is formed by connecting a low resistance in parallel with galvanometer is required to measure the current through test resistor.
