A 5 V battery is connected across the points X and Y . Assume D 1 and D 2 to be normal silicon diodes. Find the current supplied by the battery if the + v e terminal of the battery is connected to point X .

Options

  1. A~ 0 . 86   A
  2. B~ 0 . 5   A
  3. C~ 1 . 5   A
  4. D~ 0 . 43   A

Correct answer

D. ~ 0 . 43   A

Step-by-step solution

Here only D 1 will work and we know for silicon diode, potential drop on D 1 will be 0 . 7   V I = 5 - 0 . 7 10 = 0 . 43   A
