Capacitive Voltage Divider Circuit as an AC Voltage Divider
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.. Voltage divider circuits may be constructed from reactive components just as easily as …
Symmetrical bridge measures unknown capacitor by comparison to a standard capacitor. Simple "symmetrical" bridges such as these are so named because they exhibit symmetry (mirror-image similarity) from left to right. The two bridge circuits shown above are balanced by adjusting the calibrated reactive component (Ls or Cs).

A one-farad (1F) capacitor can store one coulomb (1C) of charge at one volt (1V). A coulomb is 6.25×1018 electrons. One amp represents a rate of electron flow of 1C of electrons per second, so a 1F capacitor can hold one amp-second (1A/s) of electrons at 1V.
