If voltage doubles and resistance remains constant, what happens to current?

Explanation:
Current increases. According to Ohm’s law, I = V / R, the current is proportional to the voltage when the resistance is fixed. If the voltage doubles while resistance stays the same, the current becomes twice as large: I' = (2V) / R = 2(V / R) = 2I. The current’s direction doesn’t change just from increasing the supply voltage in the same orientation, so it doesn’t become negative.
