A student is provided with a variable voltage source VV, a test resistor RT=10Ω{R}_{T} = 10Ω, two identical galvanometers G1{G}_{1} and G2{G}_{2} and two additional resistors, R1=10MΩ{R}_{1} = 10MΩ and R2=0.001Ω{R}_{2} = 0 . 001Ω. For conducting an experiment to verify ohm's law, the most suitable circuit is:

Step-by-step solution

A galvanometer is a tool used to either detect or quantify an electric current. The movement of a magnetic needle or a coil in a magnetic field, which is an essential component of a galvanometer, typically indicates the current and its strength.

Depending up on the resistance and the connectivity in the circuit, galvanometer can be used either as voltmeter or as an ammeter.

Voltmeter should have very high resistance, while ammeter should be having very less resistance.

Hence, the high resistor R1{R}_{1} should be connected in series with the galvanometer in order to measure the potential difference across the test resistor. Also, the low resistor R2{R}_{2} should be connected in parallel with the galvanometer in order to measure the current across the test resistor.

Thus, this combination will work properly.
