State ohm’s law and its limitations.

Ohm’s law: The potential difference across any two ends of a conductor is directly proportional to the current flowing between the two ends provided the temperature of the conductor remains constant.

Limitation of Ohm's Law: The limitations of Ohm's law are explained as follows: This law cannot be applied to unilateral networks. A unilateral network has unilateral elements like diode, transistors, etc., which do not have same voltage current relation for both directions of current.
