The basics of linear voltage regulators - what they do, how to wire them up, and where to find them. Then I give a basic example of how to build a 5V supply that can power USB powered gadgets. 5 volt regulators: http://www.amazon.com/exec/obidos/ASIN/B00H7KTRO6/afromods-20 This video builds on material covered in my tutorial on building unregulated power supplies: http://www.youtube.com/watch?v=cyhzpFqXwdA Webpage: http://www.afrotechmods.com/ Twitter: http://twitter.com/Afrotechmods Facebook: http://www.facebook.com/Afrotechmods/
Dear friends, Please support us at Patreon, so that we can continue our free educational service https://www.patreon.com/LearnEngineering The invention of transistors revolutionized human civilization like no other technology. This video demonstrates working of a Bipolar Junction Transistor (BJT) with it's practical applications such as transistor as an amplifier and as a switch with help of animation. Along with transistor working of diode is also explained in the video. The video covers following topics - structure of Silicon atom, doping, N type doping, P type doping, working of Diode, working of NPN transistor and dual stage amplification.

Power Transmission Engineer Lionel Barthold Explains how 3 phase, 6 phase, and 12 phase power works, advantages, disavantages, and hopes for the future. Rotating phases, form an anisotropic tube. He worked on experimental 6 and 12 phase power lines at his company Power Technologies, Inc. before it was sold to Siemens after a long successful career. The experimental polyphase lines were located in Malta, New York, not far from company headquarters in Schenectady.
MOSFETs are the most common transistors used today. Support on Patreon: https://patreon.com/baldengineer They are switches that can be used an Arduino, BeagleBone, or Raspberry Pi. This is part 2 of a 2 part series, which covers MOSFETs. (Part 1 Covered BJTs). When it comes down to it, MOSFETs are pretty complicated devices. This video will cover the basics of what you need to use them in your circuit, including calculating if you need a heat sink or not. Learn what they are and how to use them.
