In steady state, all parts of the circuit have the same current, that is the sum of all the moving electrons across any slice of the circuit gives the same result. But that doesn’t mean all parts of the circuit have the same electric field. Where there is a resistor, there is a large electric field to drive the electrons through faster - this is counter to our understanding of “resistance”, | In steady state, all parts of the circuit have the same current, that is the sum of all the moving electrons across any slice of the circuit gives the same result.

Much of our study of electric fields was focused on fields that didn’t change with time. The field was due to some static distribution of charge that didn’t move or change. However, in many situations the sources of charge will move and thus create a [[184_notes: | Much of our study of electric fields was focused on fields that didn’t change with time.
