Where I is the current flowing through the conductor in amperes (A), V is the voltage applied across the conductor in volts (V), and R is the resistance of the conductor in ohms (Ω). Mathematically, Ohm’s Law can be expressed as: In other words, if you increase the voltage across a conductor, the current flowing through it will also increase, as long as the resistance of the conductor remains constant.

The current flowing through a conductor is directly proportional to the voltage applied across it, provided the temperature and other physical conditions remain constant.

Ohm’s Law is a fundamental principle of electricity that relates the electric current flowing through a conductor to the voltage applied across it and the resistance of the conductor.
