Consider the two capacitors, C1 and C2 connected in series across an alternating supply of 10 volts. As the two capacitors are in series, the charge Q on them is the same, but the voltage across them will be different and related to their capacitance values, as V = Q/C. ...
Capacitors Explained
A system composed of two identical parallel-conducting plates separated by a distance is called a parallel-plate capacitor (Figure 4.1.2).The magnitude of the electrical field in the space between the parallel plates is, where denotes the surface charge density on one plate (recall that is the charge per the surface area ).).
The amount of storage in a capacitor is determined by a property called capacitance, which you will learn more about a bit later in this section. Capacitors have applications ranging …

If we substitute a smaller rated voltage capacitor in place of a higher rated voltage capacitor, the smaller capacitor. This can happen because of the unexpected increases in voltage. The common working DC voltage of capacitors are usually 10V, 16V, 25V, 35V, 50V, 63V, 100V, 160V, 250V, 400V and 1000V.
