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

Question

A.
Resistance is directly related to length.
B.
Resistance is directly related to the square of the length.
C.
Resistance is inversely related to the length.
D.
Resistance is inversely related to the square of the length.

Answer 1

The correct answer is:

A. Resistance is directly related to length.

When the length of a wire increases, the resistance of the wire also increases, assuming that other factors such as the material, temperature, and cross-sectional area remain constant.
