Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Therefore, V = RI where R is a constant called resistance. R depends on the dimensions of the conductor and also on the material of the conductor

Ohm's law states that the potential difference across the two points of a conductor is directly proportional to the current flowing through it i.e :-
This means that when voltage (potential difference) increases current also increases.
Factors on which resistance depends upon are:-
- Area of cross section of the conductor
- Length of the conductor.
More information:-
the above relation tells us that:-
- Resistance of a conductor is directly proportional to the length of the conductor. Which means that when the length increases, resistance also increases and when length decreases resistance also decreases.
- Resistance is inversely proportional to the area of cross section of the conductor. Which means that when the area of cross section or its thickness increases, resistance decreases and when area of cross section Decreases, resistance increases.
