Question

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

Resistance is directly related to length.
Resistance is directly related to the square of the length.
Resistance is inversely related to the length.
Resistance is inversely related to the square of the

Answer 1

A. Directly related to length of wire

Step-by-step explanation:

Plato: The length of a wire, electrons can move through a shorter wire easier than they can move through a longer wire.

Answer 2

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
