Plot a graph between potential difference V and current I through a conductor.

To plot a graph between potential difference (V) and current (I) through a conductor, we need to understand the relationship between these two quantities. In most conductors, the current flowing through them is directly proportional to the potential difference applied across them. This relationship is known as Ohm's Law, which states that:

V = I * R

Where:
V = Potential difference (in volts)
I = Current (in amperes)
R = Resistance (in ohms)

In this equation, resistance (R) is a constant property of the conductor. For a given conductor, the relationship between potential difference and current is linear, with the resistance acting as the proportionality constant.

To plot the graph, we can assume a specific resistance value and calculate the corresponding current for different potential differences. Let's assume a resistance of 10 ohms for this example. We can calculate the current for various potential differences using Ohm's Law and then plot the points on a graph.
