Question

What type of relationship exists between the length of a wire and the resistance, if all other factors remain the same?

Answer 1

Resistance of the wire can be calculated using the following rule:
R = (ρ*L) / A 
where:
R is the resistance
ρ is the resistivity of the material of the wire
L is the length of the wire
A is the area of the wire

From the above relation, we can deduce that:
The resistance of the wire is directly proportional to its length assuming all other factors are constant
