Hi everyone,


An electrical oven that is based on a a loopy bended bar in which the pan is put on or whatever works, as its name implies, on electiricity, however, since what is passing through the bar is electricity, why a person doesnt get shocked when the bar is touched by a finger of them? it only seems to cause a smack of burnt finger!

Try touching the hot wire and ground and let me know what you find.:)
 
Oven elements are coaxial in nature. There is the inner resistive heater element which is surrounded by an electrical insulator. All this is surrounded by a metal tube which is the part you see glow.

The looped heating wire, such as used in an electric stove, consists of a high resistance (typically nichrome) wire covered with a high temperature ceramic insulator. A metal shroud is then bonded over the insulated, wire. Thus the wire can pass electricity and get hot, which is transferred to the outer shroud, but it is not in electrical contact with the shroud so you don't get shocked. It's common name is calrod.
 
Too bad my toaster isn't made like that! Hey, sometimes a butter knife is the only thing available to get the toast out.:D
 
Try unplugging it and inverting the toaster. Toasters have nichrome wire, too easy to be electrocuted. Oven electrocutions occur at the rear panel or front outlet.
