In the given circuit the current through zener diode is:

Options

  1. A3 . 3   mA
  2. B2 . 5   mA
  3. C5 . 5   mA
  4. D6 . 7   mA

Correct answer

A. 3 . 3   mA

Step-by-step solution

V AB = 10   V ∴ V BC = 5   V , the current in R 1 =   I 1 = 5 500 ⇒ I 1 = 10   mA . Current in R 2 =   I 2 = 10 1500 ⇒   I 2 = 20 3 m A Current in zener diode = I 1 -   I 2 = 10 - 20 3   mA = 10 3   mA
