Answer 1

Answer:

1.Resistance of the conductor and its cross section. Thickness of the conductor and material used to make the conductor. Potential difference across the end of the conductor.

2.an electrical instrument used to control a current by varying the resistance.

Answer 2

Answer:

The resistance of a conductor depends on thickness (cross sectional area of the wire), length and temperature.

Resistivity is defined as the measure of the resisting power of a specified material to the flow of an electric current.

R=ρ

where R = Resistance of the conductor

ρ = Resistivity of the conductor

l = length of the conductor

A = Area of cross section.
