In a parallel circuit, what happens to the voltage across the loads?

In a parallel circuit, each load is connected directly across the same voltage source, which means that the voltage across each load remains constant and equal to the voltage of the power supply. As a result, if there are multiple resistive loads connected in parallel, they all experience the same voltage drop, which is why it stays the same across the loads.

The characteristic of parallel circuits allows them to provide the same voltage to each load regardless of how many devices are connected. This is a fundamental property that distinguishes parallel circuits from series circuits, where the voltage divides among the loads. Thus, maintaining a constant voltage across each load ensures that they function independently of one another.
