circuit analysis
the input voltage rises to a higher peak voltage; the capacitor is discharged by the parallel resistor and another input peak comes along; So, if your input voltage peaked once and then went to zero volts forever, the capacitor (C1) will receive that peak input voltage and then will be slowly discharged by R1.
8.3: Initial and Steady-State Analysis of RC Circuits
When analyzing resistor-capacitor circuits, always remember that capacitor voltage cannot change instantaneously. If we assume that a capacitor in a circuit is not initially charged, then its voltage must be zero. The instant the circuit is energized, the capacitor voltage must still be zero. If there is no voltage across the device, then it is ...
