Resistance is defined as the opposition to the flow of electrical current through a conductor. The resistance of an electric circuit can be measured numerically. Conductivity and resistivity are inversely proportional. The more the conductive, the less resistance it will have.
Resistance = Potential difference/ Current
The resistance of the conductor depends on the following factors:
- The temperature of the conductor
- The cross-sectional area of the conductor
- Length of the conductor
- Nature of the material of the conductor
