General Solutions: RC & RL Circuits 2/29/2012 + - C R RC Circuit + - L R RL Circuit g = g G + g ± − g G ² ³(´³´ µ )/¶ Solution steps: Choose g : RC circuits: X=Q or X=V; LR circuits: X=I Find g ± (simplifying diagram) Find g G (simplifying diagram) Find · ´¸ (for inductor/capacitor) Find τ : RC circuits: ¹ = · ´¸ º; LR circuits: ¹ = »/· ´¸ If circuit changes at ¼ ½ , use g(¼ ½ ) from prior solution for initial values
General Solutions: LC Circuits For an undamped, free (undriven) LC circuit: g G = ± cos²G + ³ sin²G Q(t) is capacitor charge at time t A and B determined by initial conditions ω is the resonant frequency; ² = 1/ ´µ Alternatively, can write: g G = ±′cos ²G + ¶ φ is the phase angle 2/29/2012 L LC Circuit C
