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 \(A, B\) and \(C\) are all true.
- B \(A, B\) true but \(C\) is false.
- C \(A, C\) true but \(B\) is false.
- D \(B, C\) true but \(A\) is false.
Answer & Solution
Correct Answer
(A) \(A, B\) and \(C\) are all true.
Step-by-step Solution
Detailed explanation
In an ideal diode \(V-I\) graph in forward bias is So, forward resistance, \(\frac{\Delta V}{\Delta I}=0\) In a half wave rectifier diode resists negative half of input cycle. Hence, current only flows for positive half cycle. When breakdown occurs, potential drop across zenner…
