Circuit board

Transformer consisting of two copper coils. One has very many windings, the thick one very few. Because of the voltage difference, the thick coil becomes very hot and even a nail can become red.

A simple tool for checking for electrical current in an extension cord... or wall outlet. The red glow indicates current.
