How does the resistance to the flow of current through a copper wire change?
Understand the Problem
The question is asking how the resistance in a copper wire changes with respect to the length of the wire. It is seeking an explanation of the relationship between resistance and length in the context of electrical properties.
Answer
It increases as the length of the wire increases.
The resistance increases as the length of the wire increases.
Answer for screen readers
The resistance increases as the length of the wire increases.
More Information
Resistance is determined by the resistivity of the material, the length of the wire, and the cross-sectional area. Longer wires have more resistance as there's more material that the current must pass through.
Tips
A common mistake is confusing the direction of the change in resistance with changes in wire diameter.
