To verify Ohm's law, a student is provided with a test resistor R_T , a high resistance R₁ , a small resistance R₂ , two identical galvanometers G₁ and G₂ , and a variable voltage source V . The correct circuit to carry out the experiment is

Correct answer

2

Step-by-step solution

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. The correct option is (c).
