A full wave rectifier is operating from 50 Hz mains, the fundamental frequency of ripple will be:
- A
100 Hz
- B
25Hz
- C
50Hz
- D
200Hz
In a full wave rectifier, we get the output for the positive and negative cycle of input a.c. Hence the frequency of the ripple of the output is twice than that of input a.c. i.e. 100Hz
In a full-wave rectifier circuit operating from a 50 Hz mains frequency, the ripple frequency refers to the frequency at which the output waveform contains variations due to the rectification process.
In a full-wave rectifier, both halves of the input waveform are rectified, resulting in a smoother output compared to a half-wave rectifier.
Since each half-cycle of the input waveform produces a ripple in the output waveform, the ripple frequency in a full-wave rectifier is twice the frequency of the input mains frequency.
Therefore, in this case, the ripple frequency would be 2×50Hz=100Hz.
This option suggests a ripple frequency of 25 Hz.
However, in a full-wave rectifier, the ripple frequency is twice the mains frequency.
Therefore, this option is incorrect.
This option suggests a ripple frequency equal to the mains frequency.
However, in a full-wave rectifier, the ripple frequency is twice the mains frequency.
Therefore, this option is incorrect.
This option suggests a ripple frequency of 200 Hz.
However, in a full-wave rectifier, the ripple frequency is twice the mains frequency.
Therefore, this option is incorrect.
