Question

A student is provided with a variable voltage source V, a test resistor R_r = 10Ω, two identical galvanometers G₁ and G₂ and two additional resistors, R₁ = 10MΩ and R₂ = 0.001Ω. For conducting an experiment to verify ohms law, the most suitable circuit is

Answer 1

Correct option is (3)

To convert galvanometer into ammeter low resistances should be added into parallel & for voltmeter conversion, a very high resistance should be added in series.
