NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Medium-Class 12
Consider a semiconductor device circuit where two diodes D1 and D2 are connected to a center-tapped transformer. If the input AC voltage at point A is positive with respect to the center tap, what will be the state of diodes D1 and D2?
A
D1 is forward biased, D2 is reverse biased
B
Both D1 and D2 are forward biased
C
Both D1 and D2 are reverse biased
D
D1 is reverse biased, D2 is forward biased
Correct Answer
Option A
Detailed Explanation
When the voltage at A is positive with respect to the center tap, D1 becomes forward biased and conducts, while D2 remains reverse biased. This results in an output current through D1 during this half cycle.
