Answer:
Ohm?s law states that the electric current flowing through a conductor is directly proportional to the potential difference across its two ends other physical conditions like temperature main constant.
\[V\propto \,\,I\]
or \[\frac{V}{I}=\text{Constant}=R\]
or \[V=IR\]
Thus, the ratio \[V:I\] is a constant. This constant. This constant called the resistance \[(R)\] of the conductor.
Circuit diagram for Ohm?s law:
Graph:
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. Thus, the ratio \[\frac{V}{I}\] remains constant. This constant is called the resistance of the conductor. The gradient of the straight line graph is related to the resistance (R) of the conductor
