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.

Html5 Version The small square at the left of each waveform vibrates at the instantaneous value of the voltage or current it represents. The subscripts "o" and "rms" stand respectively for peak value and root-mean-square value. The phase difference can be found by using the triangle H. If the inductive reactance XL is greater than the capacitive reactance XC , the supply voltage will lead the current; if the inductive reactance is smaller than the capacitive reactance, the supply voltage will lag behind the current.
The p. In other words, C and D are always in antiphase. The four RMS volatges are related by the triangle H. The curve F shows the variation of the reciprocal of the impedance against frequency.
G shows three rotating vectors phasors , their projections on the y-axis corresponds to the three instantaneous voltages. Series resonance is achieved by adjusting f, L or C such that the purple dot is exactly at the highest point of the curve F. Therefore, A and B become exactly identical, A and E are inphase. The circuit current E is the largest. At resonance, the p.
