7 Differences Between EMF and Voltage
S.NO. | EMF | Voltage |
1. | EMF (electromotive force) is the driving force that moves an electric charge through a circuit. | Voltage is a measure of the potential difference between two points in an electric circuit. |
2. | EMF is a measure of the energy provided to an electric circuit. | Voltage is a measure of the energy per unit of charge in an electric circuit. |
3. | EMF is a scalar quantity. | Voltage is a vector quantity, meaning it has both magnitude and direction. |
4. | The unit of measurement for EMF is the volt (V). | The unit of measurement for voltage is also the volt. |
5. | EMF is the energy provided to a circuit by a source, such as a battery or a generator. | Voltage is the energy difference between two points in a circuit. |
6. | EMF can be thought of as the "push" that drives electric charge through a circuit. | Voltage is the "potential" for electric charge to flow between two points. |
7. | EMF is a fundamental concept in electrical engineering.
| Voltage is a more practical concept that is used to design and analyze electric circuits. |
