Capacitor Voltage Divider Dc. Voltage dividers are fine if the output is connected to a very high impedance i e. Unlike resistive voltage divider circuits which operate on both ac and dc supplies voltage division using capacitors is only possible with a sinusoidal ac supply.

Capacitive voltage dividers consist of two capacitors.
In the top circuit it is possible to continuously draw current across the point marked in red. According to this formula the capacitor with the lower capacitance value will drop more voltage across it. This is because the voltage division between series connected capacitors is calculated using the reactance of the capacitors x c which is dependent on the frequency of the ac supply. Capacitor voltage divider in quasi dc circuit.
