When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around ...

Instead of these exotic current limiting diodes, he could have used a current source or current sink consisting of an PNP or NPN transistor respectively, a (zener) diodes, and 2 resistors.

Electronic devices use components like resistors, capacitors, transistors, diodes, & ICs. Circuit diagrams use symbols to represent these, enabling engineers worldwide to communicate & understand ...
