Quick Check on Current through Aluminum Capacitors

Quick Check on Current through Aluminum Capacitors 

One quick test of whether the current passing through an electrolytic capacitor is within bounds is to touch it after it has been running for some time (high-voltage power supplies must be turned OFF just prior to this ). If an electrolytic capacitor has been designed with the normal recommended procedures for ensuring its life, the delta between its case temperature and the ambient temperature should be almost equal to the delta between its
