Parallel circuit topology with a two-cell battery, three lamps, and a single switch controlling the entire circuit. Current flows from the battery through the switch to three parallel branches, each containing one lamp, before returning to the battery. This configuration demonstrates how parallel branches allow independent lamp operation while sharing the same voltage source. Fork this diagram on Diagrams.so to customize lamp values, add ammeters, or modify the battery configuration for classroom demonstrations. Parallel circuits are fundamental to residential wiring and industrial control systems where independent load switching is required.
