Energy can be transferred from one to the other within the circuit and this can be oscillatory. A mechanical analogy is a weight suspended on a spring which will oscillate up and down when released. This is no passing metaphor; a weight on a spring is described by exactly the same second order differential equation as an RLC circuit and for all the properties of the one system there will be found an analogous property of the other. The mechanical property answering to the resistor in the circuit is friction in the spring—weight system. Friction will slowly bring any oscillation to a halt if there is no external force driving it. Likewise, the resistance in an RLC circuit will "damp" the oscillation, diminishing it with time if there is no driving AC power source in the circuit.

Reactive power is the vector sum of the inductive and capacitive powers. The former implies that the current leads the voltage and the latter denotes that the current lags the voltage.
Because in practice the majority of applications including home and industrial circuits are parallel circuits, any circuit is categorized to be leading or lagging. If in a circuit the current leads the voltage, the circuit is said to be leading; if the current lags the voltage, the circuit is said to be lagging. In practice, most of the circuits are lagging because of the presence of electric motors, unless the effects of electric motors are compensated by inserting capacitors that introduce capacitive power to a circuit see power factor correction.
It has to be accompanied by the statement for leading or lagging. A circuit may have the same power factor in two cases, either leading or lagging. Sometimes the leading or lagging is attributed to the power factor. For example, one may say a circuit has a leading power factor of 0. Did you find apk for android?

Exemples : 1 circuit bouchon amorti.. Construction de Fresnel. A resistor-inductor circuit RL circuit , or RL filter or RL network, is an electric circuit composed of resistors and inductors driven by a voltage or current source. Introduction RLC circuits in the past and present have been source of error and inaccuracy in many major applications causing poor performance of electrical product and prototype. Recent researches in regard to this aspect seen to..
