If you double the voltage in a circuit with fixed resistance, what happens to the current?

Explanation:
Doubling the voltage with the resistance kept the same changes the current in direct proportion to voltage, because I = V/R. If you double V while R stays constant, I also doubles. For example, with R fixed at 5 ohms, increasing voltage from 10 V to 20 V makes current go from 2 A to 4 A. It can’t stay the same, halve, or drop to zero when the driving voltage increases while the resistance remains unchanged.
