Solutions

Expert Solution

Resistance is the opposition offered to the flow of current.factors which affects resistance are as follows.

a. Area of cross section: The resistance of the conductor depends upon the area of the conductor.if the conductor is thinner the resistance is more and vice versa.

b. Length of conductor: the resistance of conductor depends upon the  length of the condutor.i.e Greater the length greater will be resistance.

C.Temperature:The resistance of the conductor increases with temperature.

d. Nature of material: Different materials have different atomic structures.so they offer different resistances.
