Parallel Rlc Circuit Differential Equation. Displaystyle omega 0 frac 1 sqrt l c this is exactly the same as the resonance frequency of an lc circuit that is one with no resistor present. 0 a cdv dt il 0 v 0 r cdv dt 4 0 r.

As the admittance y of a parallel rlc circuit is a complex quantity the admittance corresponding to the general form of impedance z r jx for series circuits will be written as y g jb for parallel circuits where the real part g is the conductance and the imaginary part jb is the susceptance. Let s differentiate the general solution equation. Because the components of the sample parallel circuit shown earlier are connected in parallel you set up the second order differential equation by using kirchhoff s current law kcl.
0 a cdv dt il 0 v 0 r cdv dt 4 0 r.
0 a cdv dt il 0 v 0 r cdv dt 4 0 r. Current is same in each element. Resistor inductor and capacitor are connected in series. Because the components of the sample parallel circuit shown earlier are connected in parallel you set up the second order differential equation by using kirchhoff s current law kcl.
