The reading in the ideal voltmeter V shown in the given circuit diagram is:

Options

  1. A5 V
  2. B10 V
  3. C0 V
  4. D3 V

Correct answer

C. 0 V

Step-by-step solution

As the voltmeter is idea, no current will flow through it. Therefore, considering left loop, we can write i = E e q r e q = 8 × 5 8 × 0 .2 ⇒ I = 25 A Now, potential drop across the cell which is connected in parallel with Voltmeter, V = E - i r = 5 - 0 . 2 × 25 = 0 V
