It is the ratio of the charge flowing across the conductor to the potential applied across it. The conductors used for holding charges are called as capacitors.Capacitance formula is used in finding the capacitance of any number of capacitors in the given circuit. Why is the initial voltage at the capacitor also 30 volts? It has the 1 ohm resistor in series with the source, so surely there must be a voltage drop across that, so less voltage across the capacitor, right? From basic electronics, the formula to determine the voltage across a capacitor at any given time (for the discharge circuit in Figure 1) is: V(t) E(e-t/RC).For instance, a typical D-cell sized electrolytic capacitor may have capacitance in the range of tens of millifarads.
