How Electronic Components Work. Posted by Millie Rainer on February 8, . When the layout of a circuit board is printed chemically onto a plastic board, it is called a printed circuit board or PCB. . Thus, a transistor can store a zero when it’s off or a one when it’s on, which is the working principle of computers. Darlington Transistors.

Fuse (electrical)Wikipedia

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, and it must be replaced or .
