What Is a Capacitive Voltage Divider?
The Voltage Divider Rule is a fundamental law of electrical circuits that states the voltage (V) across a resistor in series with two other resistors is equal to the ratio of their resistance multiplied by the total voltage. In other words, V₁ = (R₁/(R₁+R₂))*Vtotal.
Capacitor Equations
The amount of voltage that a capacitor discharges to is based on the initial voltage across the capacitor, V0 and the same exponential function as present in the charging. A capacitor charges up exponentially and discharges exponentially.

What is the Function of a Capacitor?
If the voltage from the power supply drops, the capacitor can release its stored energy to compensate for the voltage drop, ensuring a stable voltage supply to the connected components. This voltage regulation function is particularly important in power supply circuits, where it helps to reduce ripple and noise in the output voltage.
Capacitive Voltage Divider
In this circuit above, the AC supply voltage is 120V. Therefore, 120V will be divided between both of these capacitors in series. To calculate how we find each voltage, we first calculate the impedances of the capacitors. Again, using the reactance formula, XC= 1/(2πfc), we calculate the 2μF capacitor to be XC= 1/(2π(2KHz)(2μF))= 40Ω.

Voltage divider
OverviewExamplesLoading effectApplicationsSee alsoExternal links
In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin). Voltage division is the result of distributing the input voltage among the components of the divider. A simple example of a voltage divider is two resistors connected in series, with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them.
