limitations of it.

Answer 1

Answer:

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

The limitations of Ohm's law are outlined below: 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. Ohm's law is also not applicable for non – linear elements.

Answer 2

Explanation:

Explanation:Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. E = I xR

Limitation:-

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. Ohm's law is also not applicable for non – linear elements.
