Ed-2 Energy Stored in a Capacitor


To demonstrate the energy stored in a capacitor


  • 8 Mfd Capacitor
  • 5 kV Power Supply
  • Insulated Screwdriver
  • Switch

Capacitor Discharge 1

Capacitor Discharge Setup.


A charging circuit charges up the capacitor to 5 kV in approximately 50 seconds. The switch is used to isolate the capacitor from the power supply. The shorting plunger is used to short the terminals of the capacitor which discharges with a mighty spark and sound effects.
