Capacitive Voltage Divider Circuit as an AC Voltage Divider
Consider the two capacitors, C1 and C2 connected in series across an alternating supply of 10 volts. 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.. Voltage divider circuits may be constructed from reactive components just as easily as …

From here, if you solve for the potential difference, we can write down this expression as q over C equivalent, the amount of charge stored in the capacitor, divided by the capacitance of the capacitor. Of course, we can write down similar type of expressions for capacitors C1, C2, and C3.
Replacing Capacitors With Different Values Guide
In the replacement of capacitors with different values, one of the most important things to consider is the type of capacitor. There are three basic types: ceramic, electrolytic and tantalum capacitors. Each type has its own unique characteristics that must be taken into account when choosing a new value for a capacitor.

8.4: Energy Stored in a Capacitor
In a cardiac emergency, a portable electronic device known as an automated external defibrillator (AED) can be a lifesaver. A defibrillator (Figure (PageIndex{2})) delivers a large charge in a short burst, or a shock, to a person''s heart to correct abnormal heart rhythm (an arrhythmia). A heart attack can arise from the onset of fast, irregular beating of the …
What Is a Capacitive Voltage Divider?
The basic function of a capacitive voltage divider is to take an input voltage and divide it into two output voltages that are proportional to each other. For example, if the input voltage is 10V then the output voltages can be 8V and 2V respectively. ... The input voltage is applied to one capacitor and then it is divided by each of the other ...
