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 galvanometers $G_{1}$and $G_{2}$and a variable voltage source V. the correct circuit to carry out the experiment is

Question

Dr. Abubacker · Accepted Answer

(c) We will require a voltmeter, an ammeter, a test resistor and a variable battery to verify Ohm’s law.
Voltmeter which is made by connecting a high resistance with a galvanometer is connected in parallel with the test resistor.
Further, an ammeter which is formed by connecting a low resistance in parallel with galvanometer is required to measure the current through test resistor.
The correct option is (c).
