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.
