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.

Description : Suppose the ammeter or voltmeter you are using in the Ohm’s law experiment does not have +ve and –ve terminal markings. How will you use such ammeter or voltmeter in the circuit?

Last Answer : Answer. We will use a typical battery to determine this. Connect them with wire and the battery if their readings are positive then we have connected them correctly and if their readings in negative then we have connected in opposite polarity.
