Current in series circuits




Current is calculated according to the resistances in a circuit. Then, why is the current same everywhere in a series circuit? Shouldn't a greater current pass through the smaller resistance? I am wondering why the total current within a circuit is calculated based on Req, if resistances don't affect the current? I=V/R?


I know similar questions has been asked, but this has a minor detail which was neither asked nor answered. I am wondering why the total current within a circuit is calculated based on Req, if resistances don't affect the current? I=V/R? Current is charge per unit time, but nobody talks about the time factor affecting the current, I know that the number of particles within a series circuit will be the same, but why is the current same?Do the particles know that there will be resistance before they even reach it?
