Question

Consider the following statements
Statement (A): The resistance of an ideal diode in forward biased condition is zero.
Statement (B): In a half wave rectifier, the load current flows only for every half cycle of the input signals.
Statement (C): In the breakdown region, a zener diode behaves as a constant voltage source.

• A. A, B \& C are all true.
• B. A, B true but C is false
• C. B true but A \& C false
• D. A, C true but B is false

Hint:

Zener diodes are voltage regulators.
Half-wave rectifier allows current in one half of cycle.
Ideal diode has zero resistance when forward-biased.

Answer 1

The Correct Option is A

- Statement A: In forward bias, ideal diode behaves like a short-circuit ⇒ zero resistance — TRUE. - Statement B: In half-wave rectifier, diode conducts in one direction only ⇒ current flows for half cycle — TRUE. - Statement C: Zener diode in reverse breakdown maintains constant voltage — TRUE.
