Question

Ohm's low is not applicable on which of following? 1AC circuit 2 conductor 3 semi conductor. 4 on conductor when is change in temerture

Answer 1

Ohm's law states that the resistance of a conductor is constant provided its physical conditions, such as temperature, remain constant.

So,

$(3) \ semi- conductors \\(4)\ change \ in \ temprature\ of\ conductors\\ohm's\ law \ law \ is\ not\ followed.$
