In a resistor following Ohm's law, increasing voltage while resistance remains constant will result in

Explanation:
Ohm's law shows current through a resistor is proportional to the voltage across it when the resistance is fixed. Since I = V/R, with R constant, increasing V directly increases I. For example, if R is 20 ohms and voltage goes from 10 V to 20 V, current goes from 0.5 A to 1 A. This linear relationship means higher voltage yields higher current, and the power dissipated increases as P = VI = I^2R. Negative current would only occur if the voltage were reversed, not simply by increasing voltage in the same direction.
