Consider a common circuit with some resistors in series. The nodes should have approximately the same potential. I know that truthfully the wire just has small resistance compared to resistors. However, even though the gradient of potential is approximately zero in a node, the same current flows through any node of a circuit as a resistor. If the gradient of potential here is zero, and is non zero across a resistor, that would mean that the electric fields are different. However, shouldn't the same amount of current be flowing across all parts of the circuit, and current is proportional to Electric field strength. Thank you. As a side question, how does it come to be that the electric field is uniform everywhere in a circuit anyways? Is it because initially it isn't, and as a result of charge buildup throughout the circuit, the circuit compensates to become equal?
