So i'm having trouble visualizing how voltage drops more within different parts of a circuit, such as a resistor vs. wire. I know all the general equations but the concept is hard for me to comprehend and I am stuck on one notion. So, say you have a simple DC circuit with just a resistor and wire connecting the two ends. Since the resistor has much more resistance than the wire, the drop in potential will be much greater across the resistor than the wire. Consequently, since the drop in potential per unit length is higher for the resistor wouldn't that mean the electric field is greater in the resistor? but how could the electric field be greater and what causes the change in E field?
