So I've been thrown onto a project to make some resistance heaters work, gotta melt some plastic for my teacher. So the heater is 800W and runs on 120 V AC, Which that should be ~6.6Amps. Now thats low enough it should (keyword should) run off of a wall outlet correct.
How would one control the temp of the thing though, I was thinking of using the kind of knob off of an electric oven. But what is that itself, just a big potentiometer? From what I've been told, working with AC isnt as simple as dropping in a resistor to limit current.
Thanks ahead of time, and sorry for whats probably a dumb question, but theres not too much running aroudn in these forums about 120VAC electronics.
Edit. To note, this is a project, for an end of year, xtra credit essay. No actual heating system will be built.
