True or False: In parallel circuits, voltage is equal across all components in the circuit.

In parallel circuits, the voltage across each component is indeed equal to the total voltage supplied by the power source. This characteristic is fundamental to how parallel circuits operate; each branch of the circuit has its own independent path for current, but they all experience the same voltage drop due to the connections being directly across the power source.

This principle stems from Ohm's Law and the definition of parallel connections, where the components share the same voltage potential. The equality of voltage across all components allows for consistent performance of devices that might be connected in such a configuration, ensuring that each device receives the same voltage regardless of differences in their individual resistances. This is why the correct answer is that the statement is true.
