In the circuit, the cells are having negligible resistances. If the galvanometer shows null defection then the value of ' V ' is

Options

  1. A12 ~V
  2. B6 ~V
  3. C4 ~V
  4. D2 ~V

Correct answer

D. 2 ~V

Step-by-step solution

Apply the Kirchoff law aligned & -12+500 i +100 i =0 & 600 i =12 & i = 12 600 =0.02 ~A & ~V = iR =100 0.02=2 ~V aligned
