parallel circuits

Side-by-side paths

Parallel circuits are electrical circuits where components connect across common points, giving current multiple independent paths to flow.

If one component fails, current continues through the others—unlike series circuits, where a single break stops all flow.

Household wiring uses parallel circuits so that one burned-out light doesn't darken the whole house.
