Choose true or false for each statement regarding the resistance of a wire. O While maintaining a constant voltage V, the current I increases when the resistivity p of a wire decreases. While maintaining a constant voltage V, the current I increases when the cross-sectional area A of a wire expands. The resistance is inversely proportional to the cross-sectional area A of the wire.
