How a Basic Electric Circuit Works - Diagram & Explanation #3772646 (License: Personal Use)

This diagram illustrates a fundamental series circuit: a battery supplies voltage, red wires conduct current, a toggle switch controls flow, and an incandescent bulb lights up when the circuit is closed. The glowing filament indicates active current, while open switch breaks the path. It visually reinforces core concepts like continuity, polarity, and energy conversion (electrical → light + heat).
