Ohm's law holds in both AC as well as in DC......
Ohms law state that at room temp the voltage is directly
praportional to current
and R is constant
but in case of transformer impedance is change from primary
to secondary so this relation not obey the situation
but the principle of transformer it transfer the energy
from one ckt to another ckt without changing frequency
means constant power in both side or equal power
power=v*i
so if v increase I decrease

if we have 320KVA Genset kindly advice how much load we can put it.
