Consider the circuit shown in the figure. Which of the following statements are correct ?

Options

  1. ACurrent through the battery is 5 A
  2. BCurrent through branch AD is 2   A
  3. CCurrent through branch BC is 3   A
  4. DThe potential difference between points D and C is 4   V

Correct answer

A. Current through the battery is 5 A

Step-by-step solution

By using the concept of Wheatstone bridge V D – V C = 0 ∴ R e q = 12 × 6 12 + 6 = 4 Ω ∴ I b a t t e r y = 20 4 = 5 A
