Diode is used as:A) An amplifierB) An oscillatorC) A modulatorD) A rectifier

Answer»

Correct Answer is: D) A rectifier

Diode is a device which allows passing a current only when it is forward biased. That's why if we use one alternating voltage source instead of a battery during the negative cycles the diode will be reverse biased and will not allow the current to flow. Hence it can be used as a rectifier.
