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:

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
