one end of capacitor wire is connected to phase and another of the capacitor wire is connected to the neutral,then remove from the socket and touch the capacitor two wire (phase and neutral )if spark is coming is good or otherwise is bad

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.
