Question

To verify ohm's law, a student is provided with a test resistor R_T a high resistance R₁ a small resistance R₂ two identical galvanometers G₁ and G₂ and a variable voltage source V: the correct circuit to carry out the experiment is

Answer 1

 The correct option

   

Explanation:

To verify ohm's law, one galvanometer is used as ammeter and other galvanometer as voltmeter. 

Voltmeter should have high resistance (connected in parallel) ammeter should have low resistance (connected in series) 

given: R₁ --- high resistance, R₂ ---- low resistance. 

∴ R₁ should be parallel to voltmeter & R₂ should be series with ammeter.
