What is the voltage drop across all resistors in a parallel circuit?

In a parallel circuit, the voltage drop across all resistors is equal across all components due to the nature of how parallel circuits operate. Each resistor shares the same two nodes, meaning each one experiences the same potential difference regardless of its individual resistance value. This consistent voltage across each component is a fundamental principle of parallel circuits, allowing for multiple pathways for current to flow.

This does not vary with resistance; in fact, while the current may differ based on the resistance of each component (Ohm's law states that current equals voltage divided by resistance), the voltage remains constant. Therefore, the correct answer highlights that all resistors in a parallel arrangement see the same voltage drop, which corresponds to the voltage of the source applied to the circuit.
