A Series RLC circuit obeys the differential equation
Lq” + Rq’+q/C = V0eiωt
In this applet you can change the values of L (in millihenrys), R (in ohms), V0 (in volts) and C (in millifarads) and f (which is ω/(2π)) by using the corresponding sliders or by clicking on the adjacent circles with arrows.
The steady state response amplitude of q here called Q0 (in tenths of a coulomb) (green) and of its current q´ denoted here by I0 (in amperes) (red) are pictured along with V0, in blue.
Below the sliders the amplitudes I0 and Q0 of current and charge, the ratio of current and voltage amplitudes |z| , the phase difference (in degrees) between the current I and voltage V, and the resonance frequency f0 are given for the settings you choose.
