If a capacitor of capacitance C (in farads), initially charged to a potential V 0 (volts) is connected across a resistor R (in ohms), a time-dependent current will flow according to Ohm’s law. Thus, during the negative half cycle of the input AC signal, only diode D 2 allows electric current while diode D 1 does not allow electric current. Since the switch is open, no current flows in the circuit (i=0) and vR=0. RC circuits have a time dependence—that is, they are not static circuits.
