Understanding DC Circuit Capacitor Behavior

Capacitors can store the charge for a long time after the supply has been disconnected. A capacitor used on three-phase line voltages can have a charge exceeding 500 V. Electric circuits such as modern switch-mode welders can have large capacitors, charged well above the supply voltage, still alive even after the plug has been removed from the ...
