I want to use power from the outlet for an electrical experiment. I will do this by using an adapter from an old appliance which steps down the volts and amps. The adapter takes regular American outlet power (120v, 60hz) and outputs 4.5 volts and .6A. Now, is this dangerous? If so, how dangerous? I heard on Mythbusters that only a couple hundred mili amps isnt too dangerous, so I'm wondering if this is. Thanks. EDIT: I'm also thinking about using higher power. Is 12volts and 1.0A still safe? How high can i go?!
