Question 13Electricity & Electronics - 1st Asst/Chief

The correct answer is D) The output ripple frequency is twice the input frequency. In a full-wave rectifier, the output ripple frequency is twice the input frequency. This is because a full-wave rectifier converts both the positive and negative half-cycles of the AC input into pulsating DC, resulting in two pulses per input cycle. Therefore, the output ripple frequency is twice the input frequency. The other options are incorrect: A) The output ripple frequency is the same as the input frequency, which is not the case for a full-wave rectifier. B) The output ripple frequency is four times the input frequency, which is incorrect for a full-wave rectifier. C) The output ripple frequency is one-half the input frequency, which is also incorrect for a full-wave rectifier.
