Electrical Short Circuit Hazard: Pencil Fire Demonstration #1438788 (License: Personal Use)

This illustration shows a standard wooden pencil with its graphite core acting as a conductor, sparking intense flames when bridging a high-current circuit via red (+) and blue (-) wires. The image emphasizes how even low-resistance everyday objects can overheat catastrophically under fault conditions. It serves as an educational tool for understanding basic electrical safety principles.

Used in science education, electrical safety training, or fire prevention guides; targets students, DIY enthusiasts, and safety officers seeking visual explanations of short circuits and thermal runaway risks.
