21.6: DC Circuits Containing Resistors and Capacitors
RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from …

What Is a Capacitive Voltage Divider?
By placing two capacitors in a series along with a resistor, you can build an efficient and effective capacitive voltage divider. The first capacitor is connected to the input voltage, while the second is connected to ground. The ratio of voltage across the two capacitors can be adjusted by varying the resistance values in between them.
Capacitor
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other.

What does the Voltage Rating on a Capacitor Mean?
A capacitor will only charge to a specific voltage level if fed that level of voltage from a DC power source. Keep in mind that a good rule for choosing the voltage ratings for capacitors is not to choose the exact voltage rating that the power supply will supply it.
