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

Explanation:
Current is set by Ohm’s law: I = V/R. When the voltage stays constant, the current is inversely proportional to the resistance. If resistance doubles, the current becomes half of what it was before. For example, with 12 volts and 4 ohms, the current is 3 amps. If the resistance increases to 8 ohms, the current drops to 1.5 amps, which is half of 3 amps. Doubling the current would require either reducing the resistance or increasing the voltage; keeping voltage fixed and increasing resistance cannot keep the current the same or increase it.
