Induced voltage



The voltage induction (so-called electromotive force: FEM) (represented Ve) is any cause capable of maintaining a potential difference between two points of an open or producing an electric current in a closed circuit. It is a characteristic of each electric generator. Generally it is explained by the existence of an electric field whose circulation Ve, \ int_S \ Ve ds \ ,, defines the induced voltage of the generator.

Units of Measure

The voltage (also called potential difference or voltage) is defined as the generator work done to pass inside the unit negative charge of negative to positive, divided by the value of said charge in coulombs, ie Joules / coulomb. It is usually measured in volts (V) equivalent to joules per coulomb (J / C), but these are SI derived unit. In the international system are the basic units per kilogram per square meter per second party cube amp: m2 · kg · s-3 · A-1
