Question

show the graphical relation betwen potential deffrence and current.

Answer 1

Relation betwen potential deffrence and current.

According to ohm's law the graph between current and potential difference is linear. The voltage is plotted on the x-axis and the current is plotted on the y-axis. This plot is also known as the V-I characteristics. The slope of a V-I graph gives the resistance of the conductor.

Or simply

As more charges carrying electrical energy passes through the conductor per unit time, more electrical energy is dissipated. Hence, the potential difference, V across the conductor increases with the current, I that flows through it.
