If voltage is increased in a circuit, what happens to the amperage?

When voltage is increased in a circuit, according to Ohm's Law (V = I × R), where V is voltage, I is current (amperage), and R is resistance, an increase in voltage will lead to an increase in current if the resistance remains constant.

This principle is fundamental in electrical circuits—when the potential difference (or voltage) applied to the circuit rises, it pushes more electrons through the circuit. As these electrons move through the resistance, the current flowing in the circuit increases.

Therefore, the correct answer reflects the direct relationship between voltage and current in an electrical circuit, illustrating how changing one variable (voltage) can influence another (current) when resistance does not change.
