When two oppositely charged bodies are connected by a wire, flow of electrons occurs from one
body to the other. This movement of electrons constitutes a flow of electric current. The wire
that allows the flow of electrons is called a conductor.
Electromotive force is an electric pressure that causes current to flow through a conduct-
ing wire. A conducting wire of large cross-sectional area allows more current to flow than
a conductor with small cross-sectional area. Therefore, a conductor with a large cross-
sectional area offers less resistance to flow of current than a conductor ...
