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.
Last Answer : Ohm's law is not applicable to semi-conductors.
Description : Ohm’s law is applicable to : (A) Semi-conductors (B) Vacuum tubes (C) Electrolytes (D) Semiconductors and Vacuum tubes
Description : is Ohms law applicable to vacuum tubes?
Last Answer : Ohm's law is not applicable to vacuum tubes.
Description : does ohm's law apply to ac circuits?
Last Answer : Yes it does, but as it is supplied with ac we will have to take impedance in account.
Last Answer : both ac as well as dc
Description : State Ohm’s law for electric circuit.
Last Answer : Ohms law -States that the current flows in a circuit is directly proportional to the applied voltage (V) and inversely the proportional resistance provided with the temperature main constant
Description : Does the linear circuit obey Ohm's law?
Last Answer : Yes linear circuit obey Ohm's law and nonlinear circuit not satisfied Ohm's law.

Last Answer : Kirchhoff's current law is applicable to 1. Closed loops in a circuit 2. Junction in a circuit 3. Magnetic circuits Which of the above is/are correct ? (a) 1 only (b) 2 only (c) 3 only (d) 1, 2 and 3
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.
Description : About trnsformer
Last Answer : Acc to Ohms law V=IR but it is only applicable when our resistance R is constant, as in case of transformer we take impedence which is equivalent to resistance is not constant it varies with system parameters that why Ohms law not applicable in case of transformer
