Question:
Ripple frequency in full-wave rectifier of input frequency $f$ is:
Ripple frequency in full-wave rectifier of input frequency $f$ is:
Show Hint
In a half-wave rectifier, ripple frequency = $f$. In a full-wave rectifier, ripple frequency = $2f$ because both half cycles are used.

- $f$
- $\dfrac{f}{2}$
- $2f$
- $4f$

The Correct Option is C
Solution and Explanation
Concept:
Electronics - Rectifiers and Ripple Frequency.
Ripple frequency is the number of output pulses produced per second after rectification.
Step 1: Understand full-wave rectifier working. A full-wave rectifier converts both the positive and negative half cycles of AC input into positive output pulses.
Step 2: Count pulses in one cycle. For one complete AC cycle: * Positive half cycle gives one pulse. * Negative half cycle also gives one pulse. So, total output pulses in one cycle = 2.
Step 3: Relate to frequency. If input AC frequency is $f$, then there are $f$ cycles per second. Since each cycle gives 2 pulses: $$ \text{Ripple Frequency} = 2f $$
Step 4: Final answer. $$ \boxed{2f} $$
Hence, correct option is (C).
