What is the necessary condition for a conductor to obey ohms law?

Open in App

Solution

Ohms Law:
Ohm's law states that if all physical conditions and temperatures remain constant, the voltage across a conductor is directly proportional to the current flowing through it.
This current-voltage relationship is written as, $V = R I$ . Here, $V$ is voltage, $R$ is resistance, $I$ is current.
