Does the length of a resistor affect the strength of its electric field?

Homework Statement

Do resistors have electric fields inside them? I'm confused because we never say voltage IN resistors. So I was wondering if charges are moving in a circuit with a resistor, would the flow of charge create E fields along the surface of resistors rather than inside?

Yes, they do. Voltage ( better to say potential difference) is always caused due to accumulation of charges. The potential difference across a resistor is due to the electric field inside it, which is caused by accumulation of charges at its end points.

So if a resistor had length L, I could use the V=Ed equation to obtain the E field?
