Capacitive Voltage Divider Equation. Capacitive voltage dividers consist of two capacitors. Reactance of 22uf 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. Voltage across cap since for a capacitor no dc current flows through but ac current does. Capacitive voltage divider example no 1 now we will calculate the voltage distribution to the capacitors 10uf and 22uf which are given in the above figure which have 10v supply voltage with40hz frequency.
By using the following equation we can find the output voltage.
Electronics capacitor capacitive voltage divider. For an ac input a simple capacitive equation is. Reactance of 10uf capacitor x c1 1 2πfc 1 1 2 3 142 40 10 10 6 400ω. As the two capacitors are in series the charge q on them is the same but the voltage across them will be different and related to their capacitance values as v q c.
