Question

what r the drawbacks of Ohm's law?

Answer 1

1. Ohm's law cannot be applied for unilateral networks (networks consisting of diodes etc).
2. Ohm's law is applicable only at stable physical conditions.
3. Ohm's law is not applicable for non-linear elements.

Answer 2

The limitations of Ohms 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. Ohms law is also not applicable for non – linear elements.
