===== Description =====

The demonstration has a variety of high-value capacitors that can be used for various purposes; in demos requiring capacitors or to just give an example of what capacitors look like. 

The capacitors pictured, from left to right, back row then front row have the following values:

  * 10mF 75V
  * 4.2mF 650V
  * 110mF 15V
  * 1µF 20,000V
  * 2700F 2.5V
  * 1F 5V

===== Purpose =====

Demonstrate the properties of capacitors, their construction and general appearance, and the variety of form factors and values they can have. 

===== Apparatus =====

  * Capacitors

===== Setup =====

Varies. You can simply show the capacitors, set them up as part of an RC or RLC circuit with the [[demonstrations:9_equipment:oscilliscopes_and_function_generators:oscilloscope:start|oscilloscope]] to show their properties or measure time constants, or charge them up and then discharge them to power something/ make a spark.

===== Notes =====

<WRAP center danger 60%>
** Danger:** Capacitors, particularly the very-high voltage ones, can store a dangerous amount of charge at a dangerously high potential. If you encounter a large-valued capacitor without properly connected shorting leads, assume it is dangerously charged until proven otherwise.

Capacitors can develop a surprisingly large charge a time after being discharged due to **[[wp>dielectric absorption]]**.
