As applied voltage increases, what happens to current?

Ohm’s law is the key idea here: current equals voltage divided by resistance. If the resistance stays constant, increasing the applied voltage raises the current in a direct, proportional way (I = V/R). So, as voltage goes up, current goes up. The other possibilities would only occur if the resistance changed or if the relationship wasn’t linear, which isn’t the case for a simple fixed resistor.
