Hi all, I just completed my first circuits course (which I did decent in). One thing that has always been bothering me is my understanding of voltage. If you have a general understanding of even the basics of circuit analysis you could probably clarify to me my understanding of voltage.
So consider the following circuit and the flow of electrons in it (not the positive charge): http://postimage.org/image/4uqaqz96p/
I have always been told that voltage is considered the "flow" or the "pushing" factor in a circuit. Kind of like gravity the charge "drops" from a point of high potential to low potential doing work, which is dictated by the voltage and the amount of charge. My understanding is that this occurs in the resistor as the electrons move from a positive to a negative terminal and that generally resistors release some sort of energy.
My first set of questions come from the source of the potential energy. My understanding is that the source is the battery (battery = voltage source)? If the electrons were to flow to the positive terminal of the battery does the battery increase the potential energy analogous to someone raising a ball? If the battery is providing an increase of potential energy, where is this energy coming from in the first place (could it be chemical energy from the battery)?
I have some more questions, but I want to tackle this bit by bit so I have a better understanding of voltage and its relation to a circuit.
Thanks in advanced and sorry if this is in the wrong section.
