  • The susceptances B1 and B2 might both be inductive; they might both be capacitive; orone might be inductive and the other capacitive.Parallel GLC circuitsWhen a coil, capacitor, and resistor are connected in parallel (Fig. 16-7), the resistorshould be thought of as a conductor, whose value in siemens is equal to the reciprocal ofthe value in ohms. Think of the conductance as all belonging to the inductor. (Thinking ofit all as belonging to the capacitor will also work.) Then you have two vectors to add, whenfinding the admittance of a parallel GLC (conductance-inductance-capacitance) circuit:Y(GjBL)(0jBC)Gj(BLBC)292 RLC circuit analysis16-6When conductance ispresent along withsusceptance, admittancevectors point “northeast”or “southeast.”16-7A parallel GLC circuit.Problem 16-13A resistor, coil, and capacitor are connected in parallel with G0.1 siemens, jBLj0.010, and jBCj0.020. What is the net admittance vector?Consider the resistor to be part of the coil, obtaining two complex vectors, 0.1– j0.010 and 0 j0.020. Adding these gives the conductance component of 0.1 0
