0Ohms Law:
George Simon Ohm, a German Physicist and Mathematician found a typical relationship between potential difference (V) and electric current (I). This relationship is known as Ohm's Law.
Ohm's Law states that potential difference across the given conductor is directly proportional to the electric current flowing through it at a constant temperature.
Let the electric current 'I' is drawn through an electric circuit and potential difference between two ends of the electric circuit is equal to 'V'.
Therefore, according to Ohm's Law,
V ∝ I Or, V = IR
Where I = electric current
V = potential difference between two ends of the electric circuit.
R = constant and is known as Resistance of the conductor.
Explanation of Ohm's Law
(a) Electric current increases with increase in potential difference.
(b) Electric current decreases with a decrease in potential difference.
