An inductor having inductance L and a capacitor having capacitance C are connected in series. The current in the circuit increases linearly in time as described by I = Kt. The capacitor is initially uncharged. (To answer the following, use L, C, K, and t as necessary.) a) Determine the voltage across the inductor as a function of time. b)Determine the voltage across the capacitor as a function of time. c)Determine the time when the energy stored in the capacitor first exceeds that in the inductor.
