To increase the current through a resistor, which action would you take?

Explanation:
Current through a resistor follows Ohm’s law: I = V/R. If you keep the resistance the same and raise the voltage, more charge flows per second, so the current increases in direct proportion to the voltage. Decreasing the voltage or increasing the resistance would reduce current. Temperature can affect resistance, but it’s not a controlled way to guarantee more current, and for many resistors, higher temperature raises resistance rather than lowers it. So applying a higher voltage is the action that increases the current through the resistor.
