When resistors are connected in parallel, the voltage drop across each resistor is equal to the applied source voltage. This principle is fundamental to understanding parallel circuits. In a parallel configuration, each resistor is directly connected across the same two points of the circuit. Consequently, each component experiences the same voltage, which is the voltage of the source supplying power to the entire set of resistors.

This consistent voltage drop occurs because the resistors share the common voltage across their terminals. Therefore, regardless of the individual resistances, each resistor will have the same voltage across it, equal to the source voltage. This relationship is a critical aspect of circuit analysis and is used widely in various applications involving electrical systems.
