Show by drawing labelled diagrams, the nature of output voltages in case of:

(i)    A half wave rectifier.

(ii)    A full wave rectifier.

(iii)    An Amplifier.

(In Each case, input in an ac voltage.)

Circuit diagrams of these devices are not required.

State one important use of a Zener diode.

State one important use of a Zener diode.

 Draw a neatly labelled circuit diagram of a Full Wave rectifier using two juction diodes.
