Transistor

Video Switching regulators make use of the energy storage properties of capacitors and inductors. A transistor, or switch, controls the charging and discharging. This method makes for an efficient regulator but can be difficult to design. Show Notes Here are links to the products mentioned in AddOhms #18:

Part 2: Active Component Symbols Schematics are the language used to describe electrical and electronic circuits. To understand how to read them, you need to know how each of the basic symbols look. Part 2 of this 3 part tutorial describes the symbols used for active components like diodes, transistors (BJTs and MOSFETs).
