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 !

does not "provide" the current - it controls it - the current comes from the power supply unit. (battery, wall-wart, etc.)

Thank you very much!
