Question:

A p-n junction diode can be used:

Options:

to convert dc voltage into ac voltage

to convert ac voltage into dc voltage

to decrease the amplitude of ac voltage

to decrease the frequency of ac voltage

Correct Answer:

to convert ac voltage into dc voltage

Explanation:

The correct answer is Option (2) → to convert ac voltage into dc voltage

A p-n junction act as a rectifier, which allows the current to flow only in one direction [forward bias], there by converting AC voltage into DC voltage.
