Question

An ideal full-wave rectifier is fed by 50 Hz AC. What is its output ripple frequency?

G1 Physics · Accepted Answer

Full-wave rectification changes negative half-cycles into positive pulses, giving two pulses per full input cycle. Thus f_out = 2f_in = 2 × 50 = 100 Hz. Final answer: Option D.
