Question
what property of a wire increases when it is made longer?
charge.
voltage.
current.
resistance
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 cross - sectional area. As length $l$ increases, resistance $R$ increases. Charge is a fundamental property of matter and not affected by wire length. Voltage and current in a circuit depend on the power source and circuit components and are not directly related to wire length in the way resistance is.
