A circuit is a loop through which current can flow. A power source, such as a battery, provides the energy for the circuit to work. Electrons flow from the negative side of the power source, through the circuit and back to the positive side of the power source. Once the electrons return to the power source, the circuit is complete.

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.
