A $60$ Hz AC supply is fed to a full-wave rectifier. The fundamental frequency of the ripple in the output is
Answer: (C) $120$ Hz
A full-wave rectifier gives an output pulse in each half cycle, so there are two pulses per input cycle: $2 \times 60 = 120$ Hz. (A half-wave rectifier would give $60$ Hz.)
