# why ohm's law is not applicable for ac circuit?

why ohm's law is not applicable for ac circuit?

Ohm's law also applicable for AC circuit but in case of AC there is impedance Z. And in case of DC there is a resistance R.

in AC E=IZ

in DC V=IR

Ohm's law is also applicable for AC circuit.

Ohm's law for AC circuit is given by,

i = v / R = Vm sinωt/R

Where i and v is the instantaneous value of current and voltage.

We can use Ohm's law for AC circuit if circuit consists of linear components and devices.
