To verify Ohm's law, a student is provided with a test resistor `R_T`, a high resistance `R_1`, a small resistance `R_2`, two identical galvanometer `G_1 and G_2`, and a variable voltage source V. The correct circuit to carry out the experiment is

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
To verify Ohm.s law one galvanometer is used as ammeter and other galvanometer is used as voltmeter. Voltmeter should have high resistance and ammeter should have low resistance as voltmeter is used in parallel and ammeter in series that is in option (c).
