PHY2061 R. D. Field Department of Physics chp36_12.doc University of Florida An LRC Circuit At t = 0the switch is closed and a capacitor with initial charge Q0is connected in series across an inductor and a resistor. The initial conditions are Q(0) = Q0and I(0) = 0. Moving around the circuit in the direction of the current flow yields QCLdIdtIR−−=0. Since I is flowing out of the capacitor, IdQdt=−/, so that dQRLLC
