- TL;DR Summary
- How the electric field varies around a circuit?

We know that E is conservative so the integral of E around a closed loop is zero. I know this helps us (in some way, that's why i'm asking) to calculate the total voltage drop around the complete circuit (which is zero).

What

Inside a battery for example there is a non-conservative E, which can't be used in the integral formula.

There

I would want to know an explanation (that makes sense) of int( E.dl) = 0 and how that relates to the change in voltage around the closed circuit.

What

*exactly*is "E" in the integral? For example, internet says "electric field is zero inside a conductor" so, then what? E. dl = 0 and we are integrating zero around the closed loop. There's nothing interesting there.Inside a battery for example there is a non-conservative E, which can't be used in the integral formula.

There

**must**be an electric field inside the conductor in some way, something must push charges.I would want to know an explanation (that makes sense) of int( E.dl) = 0 and how that relates to the change in voltage around the closed circuit.
