  1. Question 1

    Q1. A Zener diode is used for voltage regulation. What is the condition for regulation?

    • A) V_in > V_z
    • B) V_in < V_z
    • C) I_z = 0
    • D) R_L = 0

    Answer: V_in > V_z

    Explanation: Zener regulation occurs when input voltage exceeds Zener voltage, allowing current to flow through the Zener diode.
