SUMMARY
The discussion clarifies the flow of electricity in a circuit involving a battery. Current in metallic conductors flows from the negative terminal to the positive terminal due to the movement of negatively charged electrons. When a spark occurs, the electric current through air consists primarily of positively charged ions moving from the positive terminal to the negative terminal, influenced by the voltage gradient between the battery terminals.
