A 50 Hz a.c. is rectified with full wave rectifier, what is the output...
If we consider this, the output frequency is certainly twice than that of input frequency.
So, if the input frequency is 50 Hz, output frequency will be 100 Hz.
It is visible from the signal waveform shown in the image using green colour.
What happens is, the negative side of the signal appears at the positive side after the rectification. Since the signal to be rectified is usually symmetric in nature, the frequency of signal at output is doubled.
Also, rectification is a process of converting alternating current into unidirectional current. It is a part of DC power generation unit. In a direct current, we ideally require a zero frequency signal. Hence, circuits like filter circuit and voltage regulation circuit further reduce this variable voltage to a fixed voltage by stabilizing it and removing all frequency components.
