A series circuit with capacitance C, inductance L, and resistance R oscillates electrically. Assuming R 4L/C what relationship V O describes the decay of the "envelope amplitude" of the current oscillations? (infinity means proportional to) I infinity e-Rt/L I infinity e-t/(2L) I infinity e-R/(2L) I infinity e-(Rt/(2L) I infinity eRt/(2L) I infinity e-Rt/2 I infinity e-2Rt/L How much time elapses before the envelope amplitude of the current falls off to 50% of its initial value?
