In a parallel electrical circuit, which statement is correct regarding voltage?

In a parallel electrical circuit, the defining characteristic is that all components share the same two nodes, which ensures that each component experiences the same potential difference, or voltage. This means that the voltage across each resistor in the parallel configuration remains constant and equal to the source voltage. This uniformity is a key feature of parallel circuits, distinguishing them from series circuits where voltage can vary across components based on their resistance.

For example, if you have a power supply connected to multiple resistors in parallel, each resistor receives the full voltage from the power supply. This is why when analyzing parallel circuit configurations, it's understood that the voltage remains unchanged across each component, allowing for convenient calculations when determining how current will divide among the various paths based on their respective resistances.
