According to the ohms law current flowing through a conductor is directly propotional to the potential difference applied across its end provide physical condition like temperature remain the same.
Methamatecally:
V=IR
The graph of v versus I is always in straight line.. The slop of graph always give resistance.

Ohm's Law is the mathematical relationship among electric current, resistance, and voltage. The principle is named after the German scientist Georg Simon Ohm.
In direct-current (DC) circuits, Ohm's Law is simple and linear. Suppose a resistance having a value of R ohms carries a current of I amperes. Then the voltage across the resistor is equal to the product IR. There are two corollaries. If a DC power source providing E volts is placed across a resistance of R ohms, then the current through the resistance is equal to E/R amperes. Also, in a DC circuit, if E volts appear across a component that carries I amperes, then the resistance of that component is equal to E/I ohms.
Mathematically, Ohm's Law for DC circuits can be stated as three equations:
E = IR
I = E/R
R = E/I
