NEET Physics (general) MCQ Question
Type: MCQ-fact-Hard-Class 12
What is the primary function of a junction diode when used in a half-wave rectifier circuit?
A
It allows current to flow only during the forward biased state.
B
It generates alternating current from direct current.
C
It increases the amplitude of the input voltage.
D
It stores electric charge during both halves of the cycle.
Correct Answer
Option A
Detailed Explanation
A junction diode permits current to flow only when it is forward biased, which is the fundamental principle used in half-wave rectifiers to allow current during specific half cycles of an alternating voltage.
