## Ohm’s Law (D.C. Circuits)

**Ohm’s law** states that “The **potential difference** between the two ends of a conductor is directly proportional to the current flowing through it, provided it’s temperature and other physical parameters remains unchanged”.

where, R is the resistance between these two points.

## Limitations Of Ohm’s Law

Resistance, Temperature, Physical condition should remain constant.

For example **Ohm’s law** is not applicable to the circuits containing non metallic conductors, semiconductor devices e.g. P-N Diode, **Zener Diode**, voltage regulator, non-linear resistor etc.
