- Electromagnetic force
- Electromechanical force
- Electromotive force
- None of these
Hint:
EMF is the acronym for electromotive force.
The correct answer is: Electromotive force
The full form of EMF is electromotive force.
- EMF stands for electromotive force.
- This refers to the electric potential produced by either an electrochemical cell or by changing the magnetic field.
- It is an electrical act produced by a non-electrical instrument.
- It is calculated in terms of volts as electrical current.
