The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is.
Q.On what factors does the resistance of a conductor depend?
Ans: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 conductive, the less resistance it will have.
Resistance = Potential difference/ Current
Factors on which conductor depends
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
Electrical resistance is directly proportional to the length (L) of the conductor and inversely proportional to the cross-sectional area (A). It is given by the following relation.
R=ρl/A
where ρ is the resistivity of the material (measured in Ωm, ohm meter)
Resistivity is a qualitative measurement of a material’s ability to resist flowing electric current. Obviously, insulators will have a higher value of resistivity than of conductors.
