Calculate Electromotive Force (EMF)



Formula

The formula to calculate the Electromotive Force (EMF) is:

\[ E = \frac{W}{Q} \]

Where:

What is Electromotive Force?

The electromotive force (EMF) is the potential difference between two points in an electrical circuit. It represents the energy per unit charge supplied by a source, such as a battery or generator. EMF is measured in volts (V), and it indicates the ability of the source to drive an electric current through a circuit. The higher the EMF, the more electrical energy is provided for each charge that flows through the circuit.

Example Calculation

Consider an example where:

Using the formula to calculate the Electromotive Force:

\[ E = \frac{50}{10} = 5 \text{ Volts} \]

This means that the electromotive force for this example is 5 Volts.
