it is clear that volts equal to the current as per ohms law.
is it appliable to the AC power or only for DC. if it is
appliacable to AC in transformers when voltage increases
the voltage decreases ????? why??????????????

Answer Posted / ram_svepl
OHM'S LAW IS APPLICABLE YO BOTH AC AND DC.
IN TRANSFORMER THE POWER IS TRANSFERRED FROM PRIMARY TO
SECONDARY SUCH THAT FREQUENCY AND POWER REMAIN UNALTERED IN
SECONDARY AND PRIMARY.
SO IN ORDER TO MAINTAIN SAME POWER
V1*I1=V2*I2(ASSUME SAME PF ON BOTH SIDES)
SO IF V2 INCREASES THEN I2 SHOULD DECREASE CORROSPONDINGLY.

3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
