NEET Physics (general) MCQ Question
Type: MCQ-numerical-Easy-Class 12
In a p-n junction diode, what happens to the voltage across the load resistor R_L during the positive half cycle of the input AC?
A
The voltage across R_L is positive due to forward bias of diode D1.
B
The voltage across R_L is negative due to reverse bias of diode D1.
C
The voltage across R_L is zero as both diodes are non-conducting.
D
The voltage across R_L fluctuates due to alternating current flow.
Correct Answer
Option A
Detailed Explanation
During the positive half cycle of the input AC, diode D1 becomes forward biased and conducts, resulting in a positive voltage across the load resistor R_L.
