BabyGeezer:
when one is learning, you shouldn't have to apologize for ignorance - the whole point about learning something is because we are ignorant to the facts surrounding the topic !the folks here are very understanding and patient enough if you can respond to whatever further clarifications they request.
that's probably the other way around - you (ideally) want the 10W heating element.
just to clarify from your earlier post;
this --> https://www.sparkfun.com/products/10213
does not "provide" the current - it controls it - the current comes from the power supply unit. (battery, wall-wart, etc.)
Thank you very much!
