The total current supplied to the circuit by the battery is

Options

  1. A1   A
  2. B2   A
  3. C4   A
  4. D6   A

Correct answer

C. 4   A

Step-by-step solution

Let us assume that the battery of 6   V is connected across points A and B . Let the centre point be C . Using the point-potential method, the points having the same potential should have the same name. After redrawing the circuit, the figure looks as shown below, The current supplied by the battery is i = V R AB V =6  V . Now, to find the equivalent resistance between A and B , R AB = 3 ∥ R AC + R CB R AC = 6 × 2 6 + 2 R AC = 1 . 5   Ω R BC = 1 . 5   Ω R AB = 3 ∥ 1 .
