A p-n junction diode is used as?
a rectifier in a d.c circuit
an amplifier in d.c circuit
an anplifier in an a.c circuit
a rectifier in an a.c circuit
Explication
Rectification: A diode allows current to flow in one direction, making it suitable for converting alternating current (AC) to direct current (DC). Diodes are commonly used in power supplies to rectify AC voltage.
