The resistivity of a wire depends on which of the following?
(A) The physical dimensions of the wire.
(B) The voltage of the battery to which the wire is attached.
Neither.
Both A and B.
A only.
B only.
Homework Answers
The resistivity of a wire is a material property and depends only on the type of material the wire is made of, not on its physical dimensions or the voltage applied to it.
Option (A): The physical dimensions of the wire (length and cross-sectional area) affect the resistance of the wire but not its resistivity.
Option (B): The voltage applied to the wire does not affect its resistivity either.
Since neither (A) nor (B) is correct, the correct answer is:
"Neither."
