Question

what are the four things that affect the resistance of a wire?
length, weight, material, and temperature
length, height, material, and temperature
weight, diameter, material, and temperature
length, diameter, material, and temperature

Explanation:

Resistance formula \( R=
ho\frac{l}{A} \) (\(
ho \) is resistivity related to material, \( l \) is length, \( A=\pi(\frac{d}{2})^2 \) with \( d \) diameter). Temperature also affects resistance. Weight and height are not in the formula.

Answer:

length, diameter, material, and temperature
