NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Which of the following statements about the behavior of a diode in a rectifier circuit during an AC cycle is correct?
A
Diode D1 conducts during the positive half-cycle, and D2 conducts during the negative half-cycle.
B
Both diodes conduct simultaneously during the entire AC cycle.
C
Diode D2 conducts during the positive half-cycle, while D1 remains reverse biased.
D
No current flows through the load resistor during the entire AC cycle.
Correct Answer
Option A
Detailed Explanation
During the positive half-cycle, diode D1 is forward biased and conducts while diode D2 is reverse biased. In the negative half-cycle, the situation reverses, allowing D2 to conduct. This behavior aligns with the description of the rectifier circuit operation.
