- Resistance: The property of any conductor that opposes the flow of electric current through it is called resistance.
- It is denoted by R and the SI unit is the ohm (Ω).
The resistance is given by:
R = ρL/A
where ρ is resistivity, L is the length and A is the area of the cross-section.
EXPLANATION:
From the above given- formula of the resistance:
- The resistance of a uniform metallic conductor is inversely proportional to its area and directly proportional to length. So option 3 is correct.
- ρ depends upon the material and the temperature.
- The resistance of a uniform metallic conductor is dependent on length, area, and temperature also.
