Answer:

Complete step-by-step answer:

Electrical resistance is the opposition to the flow of current in the conductor. It is the reciprocal of electrical conductance.

• We know that the resistance of the conductor depends on the material used, size and shape of the material, temperature of the material.

• Thus that the resistance of the conductor depends on the material used, length of the material and area of material used ( .i.e.R=ρL/AR=ρL/A )

• where ρρ is the specific resistance or the resistivity, LL is the length of the resistance in meters and AA is the area of the resistance in square meter.

• The resistance also depends on the temperature of the conductor, when the temperature rises the number of photons in the conductor increases, and hence the collision between electrons and photons. Thus, increases in the temperature, increases the resistance of the conductor.
