Questions about ballasts (lemmy.world)

I'm using an instructable as reference for a project and it says to use anything available that draws 5-10A as a ballast. Examples were a hair dryer, I thin toaster, and also an incandescent bulb as a test article.

I don't quite understand include any of those things in the circuit. Is it as simple as ripping the guts or if a hair dryer to get to the heating element and writing it in with the exposed leads?

Any general information on ballasts that aren't for florescent lighting would be very helpful

What are you building? (I'm trying to imaging why such a thing would be needed.)

A solid state tesla coil. It's needed to limit current, and is wired in series with a rectifier to turn 120V AC into stable DC
