This relationship between voltage, current, and resistance is important in understanding how electrical circuits and devices work, and it forms the basis for many calculations in electrical engineering and physics.Īlso Read : Physics Derivation and theory questions By Dr.
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.
