I am having difficulty in understanding how heating elements and switches work to control how much heat is dissipated in the element of electric stoves or other similar settings.
From one perspective I have learned the more resistance in say a conductor the hotter the conductor itself gets. The smaller wires get hotter as thicker wire with respect to the same voltage applied to both.
I am certain that the heating element hardly has any resistance in that sense. Or if the lower resistance heating element won't get as hot as the higher resistance element.
With respect to the control switches, if they control voltage by means of having their own some sort of metallic variable resistors which in turn must get hot and get old. And if this varying voltage determines the amount of current to the heating element and not the heating element itself.
I am also wondering if a heating element with more resistance will get hotter than the one with less and what happens to resistance as the heating element gets old?
It is the type of stuff that bugs me.
