Solution

The graph proves Ohm's law. Ohm's law states that, under constant temperature and physical conditions, the current flowing through a conductor is always proportional to the potential difference across it i.e.
V ∝ I
Or , V = RI
where R is a constant of proportionality called resistance of the resistor. It tends to resist the flow of charge through a conducting wireIts SI unit is ohm (Ω).
