Cnductor size depends upon the load which in turn depends
upon the current carrying by the cable. Generally any cable
can carry current 2.5 times the cable size. Suppose 4
suare mm cable can carry 10.5 amps current.

If we impress a dc voltage of 230 V on an unloaded 230 V, 50 Hz transformer it wi A give high secondary voltage B burn out C give secondary voltage as per K D none of these
