To detect a faulty ceramic disc or paper capacitor, which of the following tests is the most preferred?
Answer: C
To detect a faulty ceramic disc or paper capacitor the preferred test is the charging-holding test: the capacitor is charged from a source and then disconnected, and a good capacitor holds its charge for a time, while a leaky or shorted one loses it quickly. An open circuit test or short circuit test only shows a gross open or short, and the capacitor action-normal charging test is used with a meter on large electrolytic types. The answer is Charging-holding test on capacitors, option (C).
