The magnitude and direction of the current in the following circuit is

Options

  1. A1 . 5   A from   B to A through E
  2. B0 . 2   A   from B to A through E
  3. C0 . 5   A from A to   B through   E
  4. D5 9   A from A to B through E

Correct answer

C. 0 . 5   A from A to   B through   E

Step-by-step solution

Let the direction of electric current in the circuit be i from A   to   B . Using Kirchhoff's law in clockwise direction, we get - i × 2 + 10 - 5 - i × 1 - i × 7 = 0 ⇒ 5 = 10 i ⇒ i = 5 10 = 0 . 5   A
