The force that causes electrons to flow through a conductor is abbreviated as what?

The force that causes electrons to flow through a conductor is abbreviated as what?

• A. E.M.F.
• B. Volt
• C. Current
• D. Resistance

Answer: (A)

The driving influence that pushes electrons through a conductor is electromotive force, abbreviated EMF. EMF represents the energy per unit charge supplied by a source (like a battery or generator) to create a potential difference that drives current. A volt is the unit of that potential difference, not the pushing force itself. Current is the actual flow of electrons, and resistance is what opposes that flow. So EMF is the term that designates the force causing the flow.
