Question

question 10 of 10 what happens to the resistance of a wire as its length increases? a. the resistance decreases. b. the resistance increases. c. the resistance alternates between high and low values. d. the resistance is not affected by a change in wire length.

Explanation:

The resistance of a wire is directly proportional to its length according to the formula $R =
ho\frac{l}{A}$, where $R$ is resistance, $
ho$ is resistivity (a property of the material), $l$ is length, and $A$ is the cross - sectional area. As length $l$ increases, with $
ho$ and $A$ constant, resistance $R$ increases.

Answer:

B. The resistance increases.
