Electromotive force is another term for what?

  1. Voltage

  2. Current

  3. Resistance

  4. Power

The correct answer is: Voltage

Electromotive force (EMF) is defined as the energy per unit charge produced by an energy source, such as a battery or generator, in an electrical circuit. In this context, EMF is synonymous with voltage, which is the measure of electric potential difference between two points in a circuit. Voltage reflects the potential energy available to move electrons through a conductor, whereas current refers to the flow of electric charge, resistance indicates how much a material opposes the flow of that charge, and power describes the rate at which energy is used or transferred. Understanding that EMF represents the driving force that pushes current through a circuit provides clarity on the relationship between EMF and voltage, making it clear why voltage is the correct response in this situation.
