Parallel RLC Circuit:
Now we connect passive elements R, L, C in parallel along with one current source.
Figure: Parallel RLC Circuit
As the circuit is parallel the voltage v across all of the elements remains same. The source current i is distributed along with the three elements by Kirchhoff's current law.
i = iR + iL + iC
i = (v/R) + (1/L) ∫ v dt + C dv/dt
Here, we describe conductance, susceptance and admittance.
Conductance G = Reciprocal of resistance
= 1 in mho
Inductive susceptance BL =1/ X L
Capacitive susceptance BC = 1 / X C
Admittance Y = Reciprocal of impedance = 1 /Z
