Hi guys, I'm trying break down a simple circuit composed of a lamp and a power source down to it's basics. So, I know that the current will flow from negative to positive. However, is it correct to say that there are more electrons before the lamp than there is after the bulb? This difference in concentration of electrons is what causes the voltage across the bulb. I know that the electrons will be moving at the same rate at all points in the circuit, but is there a higher concentration of electrons before they "meet" the bulb than after the bulb? I know some of you will laugh at such a simple question, but it's something that's been annoying me.
