Electronics: Capacitors
| |
   | Capacitors are used to store electric charge which can be released into a circuit when required. The unit of capacitance is the Farad which is a very large unit. Most commonly used capacitors are rated in microfarads - µF (millionths). Large value capacitors are often used as smoothing capacitors in A.C. power supplies. Other uses for capacitors are in timing circuits and filter circuits. |
