Cell EMF Calculator
Cell EMF calculator is used for providing the value of electromotive force (EMF) for galvanic (voltaic) cells with given electrodes potential.
EMF is known as an electromotive force. It is a maximum potential difference between two electrodes of voltaic or galvanic cell. It also defined as electric pressure or force which generates the current in a circuit. The EMF unit is volt [V].

Formula of Cell EMF Calculator
The formula to calculate the area of a parallelogram is as follows
EMFcell [V] = Ecathode [V] - Eanode [V]
Where,
A cathode = reducing electrode that releases the electron to the external circuit that's potential is in volts[V].
A node = oxidizing electrode that accepts the electron from an external circuit that's potential is in volts[V]
EMFcell = electromotive force.
Note:
If you want to calculate buffer capacity, you can use our Buffer Capacity Calculator.
Example
If we have a potential of anode is 8.5 volts and the potential of cathode is 12.5 volts then find the cell emf?
Given data
potential of anode = 8.5 volts
potential of cathode = 12.5 volts
To Find
EMFcell =?
Solution
By using the formula listed below, you can find the area of a parallelogram.
EMFcell [V] = Ecathode [V] - Eanode [V]
Putting values in the formula:
EMFcell = 8.5 - 12.5
EMFcell = 4 volts
