In the following circuit reading of voltmeter V is

Options

  1. A12 V
  2. B8 V
  3. C20 V
  4. D16 V

Correct answer

A. 12 V

Step-by-step solution

PD between X and Y is V_ X Y =V_X-V_Y=1 4 and PD between X and Z is V_ x Z =V_x-V_Z=1 16=16 ~V Now, we get potential difference between Y and Z i.e., reading of voltmeter is V_Y-V_Z=12 ~V
