Capacitive Voltage Divider: An In-depth Guide
A capacitive voltage divider is an electronic circuit that uses capacitors to divide an input voltage into a smaller output voltage. It works on the principle of capacitive reactance and is used in various applications such as signal conditioning, filtering, and impedance matching.
Capacitive Reactance
Capacitive reactance is measured in ohms of reactance like resistance, and depends on the frequency of the applied voltage and the value of the capacitor. (6–5a) X c (Ω) = 1 2 …
Understanding Capacitive Voltage Divider Circuits with Formulas
Consequently the smaller 10μF capacitor, with its higher reactance of 318.3Ω, experiences a greater voltage drop of 69 volts compared to the larger 22μF capacitor, which has a 31-volt drop and a reactance of 144.7Ω.
Calculating Capacitance and Capacitive Reactance
A capacitor is a device that can store electric charge on its conductive plates. The amount of charge (Q) that a capacitor can store depends on the voltage difference between its plates. When a capacitor is connected to an alternating current (AC) circuit, its capacitance affects how well it can store and release charge as […]

Capacitive Voltage Divider as an AC Voltage Divider
As capacitive voltage dividers use the capacitive reactance value of a capacitor to determine the actual voltage drop, they can only be used on frequency driven supplies and as such do not work as DC voltage dividers. This is mainly due to the fact that capacitors ...
8.3: Reactance, Inductive and Capacitive
For capacitors, we find that when a sinusoidal voltage is applied to a capacitor, the voltage follows the current by one-fourth of a cycle, or by a (90^o) phase angle. Since a capacitor can stop current when fully charged, it limits current and offers another form of AC resistance; Ohm''s law for a capacitor is [I = dfrac{V}{X_C},] where (V) is the rms …
