उत्तर
The ability of a junction diode to rectify an alternating voltage is based on the fact that it allows current to pass only when it is forward biased.
Explanation:
A p-n junction diode conducts current only in forward bias and blocks current in reverse bias. Because of this property, it converts alternating current (AC) into unidirectional (DC) current. This process is called rectification.
