Q9 State Ohm's law. Draw a labelled circuit diagram to verify this law in the
laboratory. If you draw a graph between the potential difference and current
flowing through a metallic conductor, what kind of curve will you get? Explain
how you would use this graph to determine the resistance of the conductor.

Answer:
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 current is directly proportional to the potential difference. Thus the ratio VI remains constant. This constant is called the resistance of the conductor. and please follow me
