RC circuits and the time constant

Circuit schematic with battery, resistor, capacitor, and a two-way switch labelled for charge and discharge positions A capacitor only charges or discharges slowly when there is resistance in series. In an RCRCRC circuit, the resistor limits the current, so the charge QQQ, voltage VVV, and current III all change with time instead of instantly.
