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.
V I
or V I = C o n s t a n t = R
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, V I = 0.4 0.1 = 4 = R
Thus, the ratio V I remains constant. The slope of the V-I diagram gives the resistance (R) of the conductor.
