    For an example of the differences between AC and DC. AC is what runs your ceiling fan, grow lights, kitchen stove, and air conditioner. DC is what you find running your flash light, walkman, and cordless drill. In other words, DC is what you find in batteries, AC is what you find coming out of your walls.

    However, there are things we plug into our walls that run off of DC and not AC. This is were a AC/DC power converter comes in. You find the AC to DC converters in compters, cordless phone chargers, battery chargers, cordless drill chargers, etc. If you have seen the converters for you car that allow you to plug in TVs, Laptop Computer Battery Chargers, those convert from DC to AC.

    Ok, that was long and probably boring.

    DC is not just batteries. Batteries are a device that stores dc power.
    I don't think many people know this but Thomas Edison worked with dc power. He wanted dc to be the main power that was to be used instead of ac. He used ac power for the electric chair he built to try and make people think that dc was safer than ac, hoping that would scare people away from using ac power. Edison's support for electrocution was motivated by a devious scheme to gain control of the electrical industry. Apparently, Edison's primary motivation for the development of the electric chair was an attempt to make people associate AC current with death, and thus increase the market for his own DC technology.
    If anybody has been schocked by both ac and dc power, they know that dc hurts alot more.

    Hence the name DIRECT current? [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img] How do you get shocked by DC Ozzy? Ac just feels like a buzzing sensation kind of hurting at the same time. It doesn't hurt but scares the #### outta ya.

    I can tell by that statement that you have never had a good shock from AC. If you ever get hit and you're grounded it's going to hurt.
    I've been shocked many times by as many as 480 volts AC. Trust me it hurts and it hurts for a long time.
    The worst shock I ever got was in a walmart.
    The second worst was a telephone.

    I've worked in alot of factorys that use dc motors, 100v dc feels like 250v ac.

    First of all, I have gotten juiced up a few times myself. When I was working offshore I grabbed a 4ga wire that was "locked out and tagged out" Should have been impossible to be live. Now, I won't go into graphic detail, but I wasn't right for days. The second I did it, I thought I was going to die. Anyway, be carefull with electricity.


    What thingy are you talking about? I think we have come to the conclusion that your pelts are fried.

    Personally, if you can find a free powersuply *I* would test them, but thats just me.

    Other than that, I don't know what your asking.

    Thanks Casper for all of your support! Also, the two heatsink fans have 3 wires with a little female hook-up thingy ma watsit (with 3 inputs at the end) and the pelt is just 2 raw wires. Will these work on the same power suppy without lots of equipment? THANKS AGAIN!!
