power factor
under periodic conditions, ratio of the absolute value of the active power P to the apparent power S:

facteur de puissance, m
en régime périodique, rapport de la valeur absolue de la puissance active P à la puissance apparente S:

λ= |P| S MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgaruWqVvNCPvMCG4uz 3bqee0evGueE0jxyaibaieYdi9WrpeeC0lXdi9qqqj=hEeeu0lXdbb a9frFj0xb9Lqpepeea0xd9s8qiYRWxGi6xij=hbba9q8aq0=yq=He9 q8qiLsFr0=vr0=vr0db8meGabaGacmGadiWaaiWabaabaiaafaaake aacqaH7oaBcqGH9aqpdaWcaaqaamaaemaabaGaamiuaaGaay5bSlaa wIa7aaqaaiaadofaaaaaaa@4128@

Note – En régime sinusoïdal, le facteur de puissance est la valeur absolue du facteur de puissance active.
