Electric Current

Question 22 • Learning Lab - US History B-CR (26-27)

Which two wire properties would provide the greatest resistance to the flow of a current?

Answer
A
short, thin
B
long, thin
C
hot, thick
D
cool, thick

Explanation

Resistance increases when a wire is longer and decreases when it is thicker. A thin wire therefore has more resistance than a thick one, and the long, thin wire combines both properties that increase resistance. The hot, thick wire has higher resistance from its temperature, but its thickness lowers resistance.
