questions about amps

i'm kind of new to this can someone tell me what in a curcuit controls how many amps are used. also if you use a resistor to lower the the amount of electrictiy in a curcuit will the amps be affected too?

It sounds as if you need a basic book on electricty to get started - I had a quick look on Amazon but couldn't see anything I recognised and so could recomend so I suggest you visit your local library first and see if you can find a book you like. There used to be a US military series called Basic Electricity which wasn't at all bad to get started with.

From your question you have quite a bit to learn but it's all good fun (and you can start playing with interesting things very early on).

Jacob,

There are plenty of online college-like courses you can take to get you started in electrical engineering. See MIT's Open Courseware

That should help you out.

Let us know how it goes.

My favorite for beginners is "Make: Electronics": http://www.amazon.com/Make-Electronics-Discovery-Charles-Platt/dp/0596153740. Good mix of practical hands-on and theory.

All About Circuits is a great online resource, too: http://www.allaboutcircuits.com/vol_1/index.html. Specific to the question about resistance and current, these are relevant entries:

Hi Jacob, I moved this discussion from the Cadsoft EAGLE forum over to this Experts space which is more relevant for the question. Cheers, Drew
