How To: Get AC current from a nine volt battery

Get AC current from a nine volt battery

Mr.G shows you an experiment in which you can create pulse DC current (which mimicks AC current) from a nine-volt battery.

This is actually a really good and useful wonderhowto. We used to do this as a way to step up voltages in radios, etc. when we ran them on batteries, via something called a "vibrator". The vibrating part was basically a relay that was oscillating fast enough to create the pulses that our instructor here generated with the file. For more info, search the web for these words: vibrator voltage conversion. Thanks for the wonderhowto, MrG.
