hello, i've been searching the forum here, many websites and books and i just dont get it. The potential difference between two points in a circuit is the work done AGAINST the electric field so who's making the work in a circuit? isnt suppose to be the Electric Field? and in a circuit the electrons flows from lower potential to higher potential so electrons is moving with the direction of the electric field no? and when we say there's a drop of potential across a resistor is it means that the work done is negative? thank you And i want to add something what is the relation between the energy gained or lost for an electron in a circuit and the work done by the electric field?
