How To Test A Capacitor With A Multimeter

For example, capacitors of 1000μF with a 20% tolerance rating mean that your results may be between 800μF and 1200μF and still show that the capacitor is in good condition. Lastly, if you get an "O.L" reading, then the meter may not have the appropriate range to measure the farads or the capacitor is faulty.

Capacitor

OverviewHistoryTheory of operationNon-ideal behaviorCapacitor typesCapacitor markingsApplicationsHazards and safety

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
