Question 7 • Crowley Credit Recovery Physics B

Which changes would cause an increase in the resistance of a wire? Check all that apply.increasing its temperaturedecreasing its temperatureusing a longer wireusing a shorter wireusing a thicker wireusing a thinner wire

Answer
A
increasing its temperature
B
decreasing its temperature
C
using a longer wire
D
using a shorter wire
E
using a thicker wire
F
using a thinner wire

Explanation

For a wire, resistance increases with temperature for typical metal wires, and it increases with length. A thinner wire also has greater resistance because its cross-sectional area is smaller. Therefore, increasing its temperature, using a longer wire, and using a thinner wire cause resistance to increase.
