everything runs on 60 hertz in the US, Europe is 50. thats why you should never, if you're traveling to Europe, take your alaram clock with you. alarm clocks measure time by the hertz which is sixty, so if you take it to europe where it runs at fifty, you will be late.


i'm an electrician

edit: correction from my previous post: it switches from postive to negative not once every second, but sixty times.
higher4hockey Reviewed by higher4hockey on . quick wiring question Hey whatsup, i am in the process of supplementing my grow with cfl's. I have bought the sockets, cords, plugs and bulbs. the problem is that the cords have no + or - markings.. Okay, there are 2 wires coming from the mogul socket, one is black, one is white, both have no markings. Also, the screws in the plug that im wiring it into are both silver so i was also wondering which prong is positive, the fat or skinny? Thanks. Rating: 5
