The current I in the given circuit will be

Options

  1. A10 A
  2. B20 A
  3. C4 A
  4. D40 A

Correct answer

A. 10 A

Step-by-step solution

The circuit can be redrawn as : We can see that the circuit is a balanced Wheatstone bridge ⇒ R AB = 4   Ω Current through cell I = V R AB = 40 4   A = 10   A
