Bin-bag Capacitor
Produced by the National STEM Centre and the Institute of Physics, this video shows how two metal foil sheets and a bin-bag can be used to show how a capacitor works. The metal foil acts as the plates and the bin-bag as the dielectric. The model capacitor can be charged and discharged as well as demonstrating what happens if a capacitor''s working voltage is exceeded.

6 FAQs about [National regulations on capacitors]
What are the requirements for a capacitor?
(4) Capacitors must be designed and constructed to safely relieve pressure that may build up in use, through a vent or a weak point in the capacitor casing. Any liquid that is released upon venting must be contained by the packaging or by the equipment in which a capacitor is installed.
What are the requirements of 173.176 capacitors?
§ 173.176 Capacitors. (a) Capacitors, including capacitors containing an electrolyte that does not meet the definition of any hazard class or division as defined in this part, must conform to the following requirements: (1) Except for asymmetric capacitors, capacitors not installed in equipment must be transported in an uncharged state .
When should a capacitor be protected against a short circuit?
(iii) When an asymmetric capacitor's energy storage capacity is greater than 0.3 Wh, or when the energy storage capacity of each capacitor in a module is greater than 0.3 Wh, the capacitor or module must be protected against short circuit .
How many capacitor banks are there in a high voltage circuit?
There may be more than one Capacitor Bank in a High Voltage circuit (i.e. Bank A, B, C) type registered device for the purpose of discharging a Capacitor Unit which may be Charged. Type Registered lead used for short-circuiting an individual Capacitor Unit.
What if the energy storage capacity of a capacitor is less than 10 Wh?
(i) Except for asymmetric capacitors, when a capacitor's energy storage capacity is less than or equal to 10 Wh or when the energy storage capacity of each capacitor in a module is less than or equal to 10 Wh, the capacitor or module must be protected against short circuit or be fitted with a metal strap connecting the terminals; or
Do I need a discharge stick on all capacitor units?
Hence the requirement to use a Discharge Stick on all Capacitor Unit(s). A Capacitor Unit is made safe by connecting together both terminals to its metal container. In some configurations one of the terminals is inherently at the container and rack potential.
