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

In a parallel circuit, the voltage across each component is indeed the same. This is a fundamental characteristic of parallel circuits, which distinguishes them from series circuits. In a parallel configuration, multiple components are connected across the same two points of a circuit. As a result, each component experiences the same potential difference or voltage, regardless of the number of components or their individual resistances.

This uniform voltage across all components is essential in applications where each component needs to operate at the same voltage level. For example, in household electrical systems, appliances wired in parallel can function independently, receiving the same voltage from the supply. The ability of each component to receive the same voltage allows for consistent performance across the circuit.
