What's up people? I'm new in this wonderful forum. I have several questions about circuits, and they are not really common, I mean, I find them somehow complicated, but I would really come to enlightenment if you guys gave me some clues. 1.- So, let's suppose we got the simplest circuit, a battery, two cables and a resistor in the middle of them, obviously everything is connected. The resistor is supposed to consume the whole voltage of the battery, no problem with that. However, the problem is that I can't understand how electrons can get back to where they started, I mean, it's a circuit, but there's a point in it where electrons loose their whole energy but still they have energy to get to the positive end of the battery. Why don't they just get stuck in the resistor? 2.- If I place an LED in the previous circuit, order doesn't seem to matter. It's irrelevant wether I place it before or after the resistance. Why is that? 3.- How can an LED light on in the circuit when the whole voltage is consumed by the resistance? Does the resistance in the LED matter? Does it act like a voltage divider then? 4.- if it was possible to follow an electron from the beginning to the end of the circuit, does it recover it's lost voltage when it gets back to the battery? Thank you in advance guys, your answers would be really helpful.
