What exactly is the electric field, and how does it transmit
Current flowing through a conductor creates a magnetic field and if that field varies in time that would induce a current in another conductor. However in regular circuits the field makes the electrons move and that is how the light bulb strays on.

For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.

As this is a stationary circuit, as many electrons are flowing out from the cathode into the wire as are flowing back into the anode. Thus at the battery cathode, electrons flow into the wire replacing those that are moved away by the electron current flow in the wire. At the anode, electrons coming from the wire enter the battery.
