what happens to the resistance of a wire as its length increases?\na. the resistance decreases.\nb. the resistance increases.\nc. the resistance alternates between high and low values.\nd. the resistance is not affected by a change in wire length.

Answer

Brief Explanations:

The resistance formula of a wire is (R = \rho\frac{l}{S}), where (R) is resistance, (\rho) is resistivity (a property of the material, constant for a given material), (l) is length, and (S) is cross - sectional area. When the length (l) of the wire increases (assuming cross - sectional area (S) and resistivity (\rho) remain constant), according to the formula (R=\rho\frac{l}{S}), the value of (R) will increase.

Answer:

B. The resistance increases.
