What is Ohm's Law graph?

Ohm’s law gives the relationship between the current and the voltage across the terminals of a metallic wire.

Mathematically, the law is represented as:

V = IR

where R is the constant that denotes resistance.

The following graph represents the current-voltage relationship of a conductor, as per Ohm’s law:
