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:
Text Solution
Verified by ExpertsC
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.
