A) rectifier
B) amplifier
C) oscillator
D) conductor
Correct Answer: A
Solution :
A \[p-n\]junction diode works as a rectifier. It offers a low resistance for the current to flow when it is forward biased but a very high resistance when reverse-biased, thus it allows current through it only in one direction and acts as a rectifier. The junction diode can be used either as a half wave rectifier or as a full wave rectifier. Note: A junction diode cannot amplify a signal.You need to login to perform this action.
