In the circuit shown the cells A and B have negligible resistances. For VA=12 V,R1=500ΩV_A=12\ \text{V}, R_1=500\Omega and R=100ΩR=100\Omega the galvanometer (G) shows no deflection. The value of VBV_B is

Multiple Choice Options

  • A 4 V
  • B 2 V
  • C 12 V
  • D 6 V

Step-by-Step Verified Solution

Since the galvanometer shows no deflection so current will flow as shown in the figure. Current, I = V A R 1 + R = 12 V ( 500 + 100 ) � = 12 600 A V B = I R = ( 12 600 A ) ( 100 � ) = 2 V
