The reading of the ammeter for a silicon diode in the given circuit is:

Options

  1. A13 .5   mA
  2. B0
  3. C15   mA
  4. D11 .5   mA

Correct answer

D. 11 .5   mA

Step-by-step solution

Given, R = 200   Ω and V = 3   V . We have to calculate the current. We know that, a potential barrier across silicon diode = 0.7   V . V = I R ⇒ I = 3 - 0.7 200 = 0 . 0115   A = 11 . 5   mA So, the current is 11 . 5   mA .
