Question 225Electricity & Electronics - QMED
70% to passAssuming a standard 60 Hz input to the circuit shown in the illustration, what would be the ripple frequency? Illustration EL-0085
A30 Hz
B60 Hz
C90 Hz
D120 Hz
AI Explanation
The correct answer is D) 120 Hz. The ripple frequency in a full-wave rectified circuit with a 60 Hz input is twice the line frequency, which is 120 Hz. This is because in a full-wave rectifier, the output alternates between the positive and negative half-cycles of the input waveform, effectively doubling the frequency. The other options are incorrect because 30 Hz is half the line frequency, 60 Hz is the line frequency, and 90 Hz is not related to the input frequency in a full-wave rectified circuit.
