Komplexe Leistung
Consider a load connected to an AC source. The voltage and currents across this load can be represented in the frequency domain. The complex power is ...
Erhaltung der Wechselstromleistung
Erhaltung der Wechselstromleistung
The principle of AC power conservation states that the complex, real, and reactive powers generated by the source are equivalent to the total complex, ...
Leistungsfaktor
Leistungsfaktor
The power factor is the ratio of the active power to the apparent power. It is determined by the phase difference between the voltage and current, which ...
Leistungsfaktorkorrektur
Leistungsfaktorkorrektur
The power transmission to a factory involves the transfer of both active and reactive power. The ratio of active to total power defines the power factor. ...
