  1. What symbol / component represents a element.

    Thanks Shane.

    ** Sometimes a resistor inside a rectangle - there is no universal
    symbol since it is not an electronic component.

    A heating element?

    I have seen these drawn like a resistor but using a "square" wave rather
    than a "triangle" wave. As Phil said sometimes shown inside a box. Sort of
    like this:

  4. Yes a heating element,
    The reason I asked is that I am just learning electronics(bit late at 42 but
    anyway), and I am trying different ways off controlling my 2 element
    still(As in parallel/series and triac). And none of the electronic programs
    or tutorials, had a symbol or any description for a heating element.
    So I have been treating them as a resistor, but to my learning mind they
    should have there own symbol.
    Which leads me to "Why are they not classified as a component"

    ** Electric heating elements are either electrical appliances or part of
    an electrical appliance - ie non electronic. My stove has a wiring diagram
    attached to the kick plate on which a zig zag resistor symbol indicates a
    heating element - each with a rating in watts beside it.

    Does the job.

    Because they are just a resistor. It doesnt seem like you you are
    doing anything precise, but if you were, simulating the non ohmic
    nature of the element would be nice, you could do so by putting in a
    light bulb rated at a much higher voltage.....

    ** Huh ? Heating elements are ohmic.

    They maintain their resistance value up to red hot as well by using
    materials like Nichrome with virtually zero tempco. Nothing like a lamp.

    Oh ok, I just assumed. Sorry for the misinformation
