Electromotive force, energy per unit electric charge that is imparted
4 FAQs about Electromotive force meaning
What is electromotive force?
It is defined as the potential difference across the terminals where there is no current passing through it, i.e., an open circuit with one end positive and the other end negative. In reality, the electromotive force is not a force but a measure of energy. The source converts one form of energy into electrical energy.
What is an example of electromotive force?
For example, a battery converts chemical energy, and a generator converts mechanical energy. The term electromotive force was coined by Italian physicist and chemist Alessandro Volta, who invented the electric battery in 1800. Suppose a circuit consists of a battery and a resistor.
What is electromotive force (EMF)?
Electromotive Force or EMF is the work done by the per unit charge while moving from the positive end to the negative end of the battery. It can also be defined as the energy gain per unit charge while moving from the positive end to the negative end of the battery.
What is a unit for electromotive force?
The common unit for electromotive force is the volt (V). This unit reflects the amount of energy (in joules) delivered per coulomb of electric charge that passes through the source. EMF represents the potential that an energy source provides to move charges through a circuit. In simple terms, it is the 'push' that causes electric charges to flow.
