What happens to amperage when resistance is decreased in a parallel circuit?

In a parallel circuit, when the resistance decreases, the total current or amperage drawn from the power source increases. This phenomenon is described by Ohm’s Law, which states that current (I) is equal to the voltage (V) divided by the resistance (R), or I = V/R.

In a scenario where multiple resistors are connected in parallel, the overall resistance is less than the smallest individual resistance. If you eliminate or reduce one of the resistors (thereby decreasing total resistance), this causes the total current in the circuit to increase because there is now a lower overall resistance for the same applied voltage. More current means that more electricity is flowing through the circuit, which manifests as an increase in amperage.

Therefore, when resistance is decreased, the amount of current that can flow through the circuit increases, making it clear that amperage will indeed increase as a result.
