Question:

To Verify Ohm's law, a student is provided with a test resistor RT, 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

Solution:

An ideal voltmeter should have high resistance and an ideal ammeter should have low resistance. G1 is acting as voltmeter and G2 is acting as ammeter.
