What happens to current when voltage increases?

When voltage increases in a circuit, the current also increases, assuming that the resistance remains constant. This relationship is described by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), formulated as I = V/R.

As voltage rises while resistance does not change, the force driving the flow of electric charge becomes greater, thereby resulting in a higher current. This is analogous to increasing water pressure in a pipe; more pressure will push more water through, given that the size of the pipe (resistance) remains consistent. Thus, the increase in voltage directly results in a proportional increase in current, highlighting the direct relationship between these two electrical parameters.
