What Is A Typical Sign That A Capacitor Is Bad Or Has Failed?
Voltage Rating: If a capacitor cannot handle the voltage applied to it, it may fail prematurely. This is often due to selecting a capacitor with a voltage rating too close to the operating voltage. Current Capacity: Similarly, capacitors have a maximum current
measurement
There are many different ways to test capacitors. Using a capacitance meter, using a DMM and an analog meter. In general, is it safe to assume that a capacitor is considered functional if it''s capacitance measurement is +- 20% of it''s declared value without doing the ohm/voltage test? doing the ohm/voltage test?
