A student is provided with a variable voltage source V, a test resistor Rr = 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
The Correct Option is D
Solution and Explanation
This question is based on conceptual clarity that we should connect ammeter in series and voltmeter in parallel to measure current and potential difference, respectively. Also, when using a galvanometer to create an ammeter, shunt resistance should be very small and should be in parallel.
When we create a voltmeter shunt should be large and in series with the galvanometer.
All these criteria are satisfied in option (2).
