A capacitor C is charged up to a potential V and connected to an inductor L and a resitor R (in series). At time t = 0 the switch S is closed.
a) Find the current in the circuit as a function of time.
b) How is this current different that it would be if there were no resistor in the circuit?
c) What is the resonant frequency of this circuit, and how does it differ from the resonant frequency of an LC circuit?
