Electromotive force (EMF) is considered under electromagnetism that is one of the basic concepts. EMF helps us to understand the process of electromagnetism. Besides, it is an important concept that is associated with the concept of voltage. Moreover, The EMF is the total energy from an energy source such as a battery or a cell. This is the way to pass energy from one source to another source. We can consider it a cell per coulomb (Q). This is the charge that is passing through it.
