Explain this clearly.

The answer should be C.

Because during +ve cycle up to 4v diode is forward bias after that it's reverse bias up to 4v decreasing of +ve cycle and it's forward bias up to 0 that o/p for +ve cycle is 4v.

And during entire - ve cycle diode is forward bias, therefore, o/p for - ve cycle is - 16.

Yes it is shunt clipper circuit.

During the +ve 16v half cycle, the diode will be reverse biased so +16v goes to the output.

During the -ve 16 we cycle, a 4 volt battery connect in series with diode in opposite direction so 16-4= 12volt is short by forward biased diode so 16-12 = 4 volt in negative.

So 16 in positive and 4 volt in negative.

During the +ve 16v half cycle, the diode will be reverse biased so +16v goes to the output.

During the -ve 16v half cycle, the diode will be forward biased then acting short and the output will be taken from the 4v battery and appears at the output as -4v.

Sameer is right, this is a shunt or parallel clipper.

Its a parallel clipper.

Thank you umesh.

When input is less then -4v, the diode is on and output is -4v.

When input is greater then -4v, the diode is off and input is appear across output peak value of output=16v.

How can it be -4v during negative half cycle ?
