@Snehanjali basa.

First half(0-180)..
2nd half (180-390).
Center tapped (common terminal help us to split the wave cycles). If don't use this tapp the output will be sinewave.

It is true answer.

CENTER TAP TRANSFORMER WORKS FOR ONLY HALF CYCLE OF FULL WAVE THAT IS 180.

180 degree phase shift takes place due to the common terminal.

Transformer having two winding. At the secondary winding, one common terminal is divided the winding into two equal half winding. The 1st half for 0-90 degree (+ve half cycle) and another half for 90-180 degree (-ve half cycle). And that common terminal is called as center tapped terminal. Like that centered tapped transformer is required for 180 degree input to rectify.

If we does not use common terminal then what will be the phase shift.

In center tapped transformer, it gives both positive and negative amplitudes with respect to the common terminal. So this will become 180 degree i/p to the rectifier.

Explain the operation of center tap transformer.

Centre tap transmformer having three terminal one common terminal so it gives 180 degree input to rectfier.

The centre tap will act as a common terminal between the diode hence we will get a 180 degree input to a rectifier.
