How to Test a Capacitor?
Turn on the power supply and measure the time taken for the capacitor to charge to 63.2% of the supply voltage. For example, if the supply voltage is 12V, then 63.2% of this is around 7.6V. From this Time and Resistance, measure the Capacitance and compare it with the value printed on the capacitor.
Basic technical data of capacitors
Each capacitor is designed for a particular rated voltage, which it must stand up to without adverse effect during continuous operation. However, this only applies to ambient temperatures of < +85 C; at higher temperatures the maximum permissible voltage or voltage limit for continuous operation is reduced by voltage derating. ...
