DC-to-DC Capacitor-Based Power Transformation
This paper explores the prospects of capacitor-based transformation of power from one voltage level to another without an intermediate magnetically-based transformer.
Inductor and Capacitor with a DC supply
As the capacitor charges, the voltage difference decreases and, therefore, the current, (Vbat-Vcap)/r, decreases. In your circuit, the capacitor is connected in series with the inductor, which, as you''ve pointed out, will initially behave as an open circuit, so the initial current through the capacitor, determined by the inductor, will be zero.

Capacitors
The current flowing in this circuit can be calculated using the definition of current, and the charge on the capacitor. Current is the rate of charge passing past a point, which is the same in this case as minus the rate of charge left on the capacitor - the capacitor losing charge corresponds to a positive current flowing from its positive plate to its negative plate.
