How does Kirchoff's Voltage Law apply to parallel circuits?

In parallel circuits, Kirchhoff's Voltage Law states that the voltage across each branch is equal to the total voltage supplied by the source. This is because all components connected in parallel share the same two node points, ensuring that the potential difference across each component is the same.

This principle underlines the operation of various electrical devices and components that are connected in parallel, allowing each device to function properly without affecting the voltage seen by the others. It is crucial for ensuring that devices operate efficiently and safely, as they all receive the same voltage level from the source.

The other options do not accurately align with the principles defined by Kirchhoff's Voltage Law in the context of parallel circuits. The law fundamentally emphasizes that while current may vary among branches due to differing resistances, the voltage remains consistent across all paths, reinforcing the rationale for the correct answer.
