Answer Posted / aryan

when we give supply to transformer transformer charge and
flux is produced and when the supply is cutoff some flux is
been remained which is known as residual flux.

when we again charge the transformer the flux produce is
combination of flux and residual flux and the current
produced due to it is known as inrush current
