J4-32. Discharge Of Capacitor With Bang
Purpose
To demonstrate that capacitors store electrical energy.
Equipment
3500 microfarad capacitor, 100 volt battery pack, large beat-up screwdriver.

Description
A 3500 microfarad capacitor is charged to 100 volts using the battery pack. Discharging the capacitor with the large screwdriver produces a very loud BANG. Scare the whatever out of your students: tell them to listen carefully for the sound before discharging the capacitor.
