Hi, I need some clarification regarding electric current and why charge flows in a conductor when connected to an EMF source. I was under the impression the EMF source (battery) produced electrons which were 'ejected' into the conductor, these electrons would then flow around the circuit toward the positive end of the battery. Reading some information recently, I was given the impression that: conductors (metals etc) have free moving electrons in their lattice which when a potential difference is applied are stimulated to move toward the positive terminal of the battery, they are then reapplied at the negative end and continue to flow around the circuit according to the conductor's resistance value. The volts of the battery is just a measure of the extent of potential difference between the positive and negative terminals of the battery which dictates the amount of energy each coulomb of charge are given and how rapidly they flow around the circuit. Is this so? Clarification will be much appreciated. Thanks.
