The unit of electromotive force (emf) is - (a) volt (b) Newton (c) Joule (d) coulomb

Unit of Electromotive Force

Electric potential creates electromotive force. Therefore, it will have the potential difference or electric potential unit. Volt is the symbol for electrical potential. As a result, the unit of the Electromotive Force will be the Volt. The SI unit for force is Newton, while the electric potential is the equivalent of electromotive force, which is not a force. The SI unit for energy is the joule. The SI unit for the charge is the columb.

• Magnetic induction is another way to induce emf into a conductor.
• Alessandro Volta, who created the first battery in the 1800s, is credited with coining the phrase electromotive force.

So, option 1 is Correct.

Summary:

The unit of electromotive force (emf) is - (a) volt (b) Newton (c) Joule (d) coulomb

Electromotive force (emf) is measured in volts. Electromotive force, or Emf, is the name given to the produced electric potential. It can develop within an electrochemical cell with the aid of chemical processes. Emf is not a force, despite what its name might imply.
