How to check it good or bad capacitor..

Answer / harishdarade563

Firstly check out the rating of capacitor you want to check.According to voltage rating given on capacitor, apply the voltage to its two terminals(Note :Do not apply the voltage more than rating voltage,otherwise it will make a short circuit,less voltage can be applied) and then short those terminals.if spark between terminals is observed it is good otherwise it is bad.

Answer / k.prakashchandra

Do not give supply directly but through a bulb. It may be shorted or you may exceed the rated voltage . If the capacitor is good the brightness will be less and you can also test for stored energy
