So recently in my EE class, we were taught you can use capacitors in series as a voltage divider. When I thought about it, it seemed like a way  Capacitive voltage divider power supply. This article explains capacitive voltage dividers and how voltage is divided up with series capacitors. Resistive capacitive voltage dividers type ROF (RC divider) are used in high voltage networks within the – kV range. They divide the primary volta-.

Why aren't capacitive voltage dividers more common?

It seems like they would be a much better solution than resistive voltage dividers with almost no loss, and I'm capacitive voltage divider of using it in place capacitive voltage divider a linear regulator in one of my electronics projects since the output voltage doesn't need to be very exact.

When the shaft of the potentiometer is rotated the resistance it produces either increases or decreases, the change in resistance corresponds to the angular change of the shaft.

Voltage divider - Wikipedia

If coupled with a stable voltage reference, the output voltage can be fed into an analog-to-digital converter and a display can capacitive voltage divider the angle.

Such circuits are commonly used in reading control knobs.

Note that it is highly beneficial capacitive voltage divider the potentiometer to have a linear taper, as the microcontroller or other circuit reading the signal must otherwise correct for the non-linearity in its calculations. High voltage measurement[ edit ] High voltage resistor divider probe.

A voltage divider can be used to scale down a very high voltage so that it can be measured by a volt meter. The high voltage is applied across the divider, and the divider output—which outputs a lower capacitive voltage divider that is within the meter's input range—is measured by the meter.

Voltage divider

High voltage resistor divider probes designed specifically for this purpose can be used to measure voltages up to kV. Special high-voltage resistors are used in such probes as they capacitive voltage divider be able to tolerate high input voltages and, to produce accurate results, must have matched temperature coefficients and very low voltage coefficients.

Just like resistors, capacitors placed in series with a voltage source form a voltage divider network. Capacitive networks, however, are a little more complex than plain resistive networks, because capacitors are reactive capacitive voltage divider.

This means that the resistance which capacitors offer in a circuit is dependent on the frequency on the input capacitive voltage divider into the circuit. Resistors are nonreactive devices, capacitive voltage divider their resistance values don't change depending on the frequency of the input signal.

Therefore, voltage is inversely proportional to the capacitance value of the capacitor. So, the capacitor with the smaller capacitance will have the greater voltage, and, conversely, the capacitor with the greater capacitance will have the smaller voltage.

Below is an example: The supply DC voltage in the above circuit is 15V.
