EMF Calculator


Our online emf calculator helps you measure the electromotive force in volts.

Electromotive force also known as EMF can be explained as the energy supplied by a battery or a cell per coulomb of charge that passes through the battery. The emf is measured in measured in volts.

The formula to calculate electromotive force is given below:

Electromotive Force Formula


where,
ε = Electromotive force [volts]
I = Current [amps]
R = Resistance of load in circuit [ohms]
r = Internal resistance of cell [ohms]

Input the values in the below emf calculator and click calculate to get the output.




Current (I): [amps]
Resistence of load in circuit (R): [ohms]
Internal resitance of cell (r): [ohms]
Electromotive force (ε): [volts]
