If caps are in parallel than total parasite resistance and inductive impedance would be halved if used two caps of the same value and same manufacturer. The charge that flows is the same for both capacitors because they are in series. A short answer is that every series resistor in a circuit will have it's own voltage drop and the capacitance will be based on the voltage difference on each of the plates (measured before and after the capacitor). You would usually want to have a current limiting resistor in series with the LED to control the amount of current flowing through it, else the LED will burn due to it exceeding its current limit. In the following series circuit examples, a 1 Ω resistor (R 1) is placed in series with the inductor and capacitor to limit total current at resonance.
