Answer Key : (c) -

(c)

Total resistance of the circuit

 Main current

Combination of voltmeter and resistance is connected in series with , so current through  and this combination will be same

Since the resistance of voltmeter is also , so this current is equally distributed in  resistance and voltmeter [  through each]

P.D. across  resistance



Next Question :

5 cells, each of emf  and internal resistance  are connected to an external circuit of resistance of  Find the current through external circuit

a)

b)

c)

d)
