The series combination of a resistor and capacitor has a greater
practical importance than does the combination of a resistor and
an inductor.
§ 5-3 The source-free RC circuit
We shall assume an initial stored energy in the capacitor:

Many of the circuits for which we would like to find the
natural response contain more than a single resistor and
capacitor,=> An equivalent circuit consisting of only one
resistor and one capacitor.
