In the given circuit, the voltage across load resistance ( R L ) is:

Options

  1. A8 . 75 V
  2. B9 . 00 V
  3. C8 . 50 V
  4. D14 . 00 V

Correct answer

A. 8 . 75 V

Step-by-step solution

Both diodes are in forward bias. In forward bias, potential drop across G e and S i will be 0 . 3 V & 0 . 7 V respectively. Therefore, current in the circuit i = 15 - 0 . 3 - 0 . 7 4 × 1000 = 3 . 5 mA Required potential drop across R L , V L = i R L = 3 . 5 × 10 - 3 × 2 . 5 × 1000 V = 8 . 75 V
