Concept:A full-wave rectifier rectifies both half-cycles of the input \( \text{AC} \) waveform into positive output pulses, doubling the output pulse repetition rate relative to the input line frequency.
Formula:$$f_{\text{out}} = 2 \times f_{\text{in}}$$
Solution:- Given input frequency: \( f_{\text{in}} = 60\text{ Hz} \).
- For a full-wave rectifier: \( f_{\text{out}} = 2 \times 60\text{ Hz} = 120\text{ Hz} \).
- The load receives two output pulses per input cycle period \( T = \frac{1}{60}\text{ s} \).
Why other options are incorrect:- Option A: \( 30\text{ Hz} \) is half the input frequency, which would indicate subharmonic frequency division.
- Option B: \( 60\text{ Hz} \) is the output ripple frequency of a half-wave rectifier, not a full-wave rectifier.
- Option C: \( 90\text{ Hz} \) is an incorrect multiple (\( 1.5 f_{\text{in}} \)).
