An ideal Zener diode with breakdown voltage of -3 V is reverse biased with a negative input voltage V_i=-5 V. The magnitude of voltage difference between points B and A is :

Options

  1. A0 V
  2. B3 V
  3. C2 V
  4. D1 V

Correct answer

C. 2 V

Step-by-step solution

Given that the Zener diode is reverse biased with an input voltage of magnitude |V_i| = 5 V. The breakdown voltage of the ideal Zener diode is |V_Z| = 3 V. Since the applied voltage is greater than the Zener breakdown voltage ( 5 V > 3 V), the Zener diode operates in the breakdown region. In the breakdown region, the voltage drop across the ideal Zener diode remains constant at its breakdown voltage. Therefore, the potential difference between points C and B is V_ CB = 3 V. The total voltage is applied across the s
