Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is V=IR
V=voltage
I=current
R=resistance
Answer:
1)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.
2) Ohm’s law is also not applicable for non – linear elements.
Non-linear elements are those which do not have current exactly proportional to the applied voltage, that means the resistance value of those elements changes for different values of voltage and current. Examples of non – linear elements are thyristor, electric arc, etc.
