Hey everybody,
I've been working on a side project of making biodiesel and I have hit a wall regarding making a heating element for it. Basically, i need to heat about a gallon of cooking oil to ~150 degrees farenheit and i've been trying to figure out how to make a heating element for it and it doesn't make any sense. Do you get more heat from a circuit if you have high or low resistance?
Going back to the topic of the thread, I bought a transformer for bell chimes, 8 volts 10 VA (is VA the same as Watts?) and i hooked it up to an extension cord and plugged it into an outlet and ran a guitar string across it because i read that you can use guitar strings to heat up and cut stuff (such as foam). It got pretty hot but i figured it could use more power so i hooked it up to the 24V 20VA screw on the transformer instead and connected it. Nothing happened. I got my multimeter out and checked and the primary circuit of the transformer was somehow no longer working. I got a new one now but i can't figure out what I did wrong. I didn't even know it was possible to break the primary coil of a transformer when it was plugged in to a proper power source.
Any suggestions or tips on how to make a heating element and how not to break my new transformer would be appreciated. I really don't know much about electronics so any input would be appreciated.
Thanks,
Sirnobody
