Insert the information in the form and the calculator will determine the electromotive force.


What is the electromotive force?


Electromotive force (EMF) is an energy transfer to an electric circuit per unit of electric charge. It is measured in volts.


How to calculate electromotive force?


To calculate electromotive force you should use the following formula:
electromotive force = current * (resistence of load in circuit + internal resitance of cell)


Why use electromotive force?


The electromotive force (EMF) is used in order to convert energy from one form to another.
