The same voltage appears across the capacitor, V C = Q/C. The capacitor acts like a poor battery that "dies" quickly by giving up all its stored charge. The charge on the capacitor at a given time is given by Q = Q o!!!!" where Q o is the charge stored on a capacitor initially. Since V C = Q/C, the voltage across the capacitor also decays ...
