If A.C is applied to anode of a diode then current will
flow for each positive half cycle through the terminal and
no current will flow for negative half cycles,A.C is
converted into a unidirectional current Hence,It will be
rectified

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
