Why does a capacitor block DC and not AC? [duplicate]
The ratio of current to voltage is large when the frequency is large and small when the frequency is small. At the extremes we say that a capacitor acts like an open circuit at DC and a short circuit at high frequencies. This means that at DC, you can put a large voltage across a capacitor without current flowing through it.

Introduction to Inductors and Inductance | Basic Direct Current …
Inductors oppose changes in current over time by dropping a voltage. This behavior makes inductors useful for stabilizing current in DC circuits. One way to think of an inductor in a DC circuit is as a temporary current source, always "wanting" to maintain current through its coil as a function of the energy stored within its magnetic field.
