A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery, or like other types of rechargeable energy storage system. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. (This prevents loss of information in volatile memory.)

19.5: Capacitors and Dielectrics

The unit of capacitance is the farad (F), named for Michael Faraday (1791–1867), an English scientist who contributed to the fields of electromagnetism and electrochemistry. Since capacitance is charge per unit voltage, we see that a farad is a coulomb per volt, or

For instance, an electrolytic has its values printed on the body along with the pins. Some have theirs represented in PF, uF, KPF, and more. A black band is also used to show the negative terminal of the capacitor. Get Your …

Basic Introduction to Filter Capacitor

Ⅰ Introduction A capacitor is two conductors that are close to each other and insulated from each other. The filter capacitor refers to an energy storage device installed at both ends of the rectifier circuit to reduce the ripple coefficient of AC pulsation and improve the efficient and smooth DC output. ...

Component Orientation and Polarity

An arrow band with a ''-'' sign represents the negative polarity on a capacitor. Radial surface-mounted capacitors use color coding to indicate polarity; a small black section on top marks the negative terminal, while a gray section indicates the positive terminal.
