Part of Lesson Plan: Power Up! - Power Supplies

Activity Overview / Details

Display the cartoon in class as the students enter.  They will get the idea that today's lesson is going to have something to do with power or electricity.  You can discuss with them why power is important, how it affects their everyday life.  How long have they ever had to go without power?  How well can they function (eat, entertain themselves, shower, etc) without power?

Video - show video on testing a power supply with an inexpensive Power Supply Tester that can be picked up on ebay or a PC tool website like newegg.com.  The video shows a simple way to diagnose a bad power supply, a valuable tool any PC Repair tech should have in their pocket. 

Remind students that any time they are dealing with power supplies, they are working with electricity, and they must take all the proper safety precautions.
