How do we calculate EMF?
We can easily determine the EMF of the cell or battery by measuring the voltage across the battery using the voltmeter.
The image showing the circuit diagram is given below,
Electromotive Force
Electromotive Force or EMF is the work done by the per unit charge while moving from the positive end to the negative end of the battery. It can also be defined as the energy gain per unit charge while moving from the positive end to the negative end of the battery.
The battery or the electric generator generates the electromotive force which causes the current to flow in the external circuit. These devices use another form of energy and convert them to electric energy.
Let’s learn more about Electromotive Force, its unit, and others in this article.
