The electromotive-force equation of the alternator will be first deduced, and subsequently that of the continuous-current machine.
The fundamental “electromotive-force equation” of the heteropolar alternator can now be given a more definite form.
electromotive force e·lec·tro·mo·tive force (ĭ-lěk'trō-mō'tĭv)
The energy per unit charge that is reversibly converted from chemical or other forms of energy into electrical energy in a battery.
|electromotive force |
Electric potential or voltage. Electromotive force is not really a force, but a measure of how much work would be done by moving an electric charge.
