6 FAQs about [Polar capacitors can be connected in series to divide voltage]
What is a capacitive voltage divider?
This capacitive reactance produces a voltage drop across each capacitor, therefore the series connected capacitors act as a capacitive voltage divider network. The result is that the voltage divider formula applied to resistors can also be used to find the individual voltages for two capacitors in series. Then:
Does a capacitor divider work as a DC voltage divider?
We have seen here that a capacitor divider is a network of series connected capacitors, each having a AC voltage drop across it. 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.
Which capacitors are connected in series?
The two capacitors which are connected in series have the capacitance values of 10uF and 22uF respectively. Here the circuit voltage is 10V,this voltage is distributed between both capacitors. In the series connection all the capacitors have same charge (Q) on it but the supply voltage (V S) is not same for all capacitors.
Why does a capacitive voltage divider always stay the same?
Because as we now know, the reactance of both capacitors changes with frequency (at the same rate), so the voltage division across a capacitive voltage divider circuit will always remain the same keeping a steady voltage divider.
What is the dividing rule for a capacitor?
Q=C/V, for series connection, the charge is constant for all capacitors. Capacitor and voltage are in an inversely proportional relation. The higher capacitor has less voltage. From dividing rule = 4.420Ω + 13.26Ω = 17.68 Ohms. It can be used to reduce voltage to measure high-level voltage. It can measure the resistance of the sensors.
Does a capacitive voltage divider network change supply frequency?
