Question

Explain the factors that influence the resistance electrical cond

Answer 1

factors are

temperature

directly proportional to length of a conductor

inversely proportional to area of crossection of a conductor

Answer 2

There are several factors that affect the resistance of a conductor ;

↪ material, eg copper, has lower resistance than steel.

↪ length - longer wires have greater resistance.

↪ thickness - smaller diameter wires have greater resistance.

↪ temperature - heating a wire increases its resistance.
