which changes would cause an increase in the resistance of a wire? check all that apply. increasing its temperature decreasing its temperature using a longer wire using a shorter wire using a thicker wire using a thinner wire

Answer

Brief Explanations:

The resistance formula of a wire is $R = \rho\frac{l}{A}$, where $\rho$ is the resistivity (which increases with temperature for most materials), $l$ is the length, and $A$ is the cross - sectional area. Increasing temperature increases $\rho$, increasing length $l$ increases resistance, and decreasing cross - sectional area (using a thinner wire) increases resistance.

Answer:

increasing its temperature, using a longer wire, using a thinner wire
