According to Ohm's law, when other physical parameters like temperature remain constant, the electric current flowing through a conductor is directly proportional to the potential difference across its two ends.
or or V =IR Thus, the ratio V : I is a constant. This constant called the resistance (R) of the conductor. Circuit diagram for Ohm's law : Explanation : If a graph is drawn between the potential difference (V) and current (I), the graph is found to be a straight line passing through the origin. This shows that the current is directly proportional to the potential difference. Calculating the slope of the graph, Thus, the ratio remains constant. The slope of the V-I diagram gives the resistance (R) of the conductor.
