If input frequency of a full wave rectifier be n, then output frequency would be - (1) n/2 (2) n (3) 3n/2 (4) 2n

1 Answer

Answer :

(4) 2n Explanation: The frequency of a full-wave rectifier is double that of the input, if the input is a sine wave. A full-wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output. Fullwave rectification converts both polarities of the input waveform to DC (direct current), and yields a higher mean output voltage.
