Question

For the given circuit, R = 125 Ω, RL = 470 Ω, Vz = 9V, and $I_z^{max}$= 65 mA. The minimum and maximum values of the input voltage ($V_i^{min}\ and\ V_i^{max}$) for which the Zener diode will be in the 'ON' state are

• A. Vimin = 9.0 V and Vimax = 11.4 V
• B. Vimin = 9.0 V and Vimax = 19.5 V
• C. Vimin = 11.4 V and Vimax = 15.5 V
• D. Vimin = 11.4 V and Vimax = 19.5 V

Answer 1

Answer: (D)

Vimin = 11.4 V and Vimax = 19.5 V

Answer 2

The correct answer is (D) : Vimin = 11.4 V and Vimax = 15.5 V
