Which of the following circuits provides full wave rectification of an ac input?

To obtain full wave rectification, we require

For the given circuit shown in fig, to act as full wave rectifier :– a.c. input should be connected across ................. and ..................... the d.c. output would appear across ................ and .....................

For the given circult shown in fig to act as full wave rectifer , the ac input should be connected across …… and ……. And the d. c output would supplied across …….. And ……….

What is rectification? With the help of labelled circuit diagram explain half wave rectification using a junction diode.
