Electrive stove top resistance

  1. Oct 25, 2012 #1
    Hi all. Electric stoves work by running a current through highly-resistant coils, correct? Why, however, does touching the coils not deliver one a shock (considering that a person would be lest resistant than the coils)?

    Because the current carrying part of the element is electrically insulated from the visible (touchable) surfaces.

    The insulation is in the form of a ceramic powder which can take any temperature that the heating element can reach and is 'fluid' enough to allow for quite a lot of expansion and contraction plus physical deformation. (Same technique as in fire proof cabling)
