Question

Explain the term resistance of the conductor name two metals which offer very high resistance and two metals which offer very low resistance write the factor in which the resistance of the conductor depends.

Answer 1

Resistance is the obstruction offered by throughout the conductor in an electric circuit.
Factors
1)Nature of the material
2)Length
3)Temperature
4)Cross section area
High resistance -Nichrome
Low resistivity-Gold,Silver

Answer 2

Resistance of a conductor refers to the opposition to the flow of charge as provided by the conductor. Higher resistance results in less current flow and vice versa.

Two metals offering very high resistance are tungsten and bismuth.

Two metals offering very low resistance are silver and copper.

Resistance of a conductor is given by

R = ρΙ/Α

Where ρ= resistivity of the conductor. It is an intrinsic property that varies from conductor to conductor.

l = length of the conductor

A = Area of cross-section of the conductor.
