Question

What is the resistance of a conductor mention the factor of the resistance of a conductor depend

Answer 1

resistance is the obstruction in the flow of current in a conductor.

R∝L

R∝1/A

⇒R∝L/A

⇒R=ρL/A       unit is Ω (ohm)

L is length of conductor

A is area of cross section

ρ resistivity of conductor . its unit Ωm

Answer 2

The hindrance developed in the path of flow of electric charges is called resistance.

Resistance of a conductor depends upon :-

• Nature of material

• Length of wire

• Area of cross section of wire
