Figure 1 is a sample circuit which can be configured to measure the applied voltage and current draw of a capacitor. Before applying any voltage to a capacitor, always test it for any shorts.

How to Check a TV Capacitor. A capacitor is an electrical component that stores an electric charge and is used in filter circuits, since AC signals pass through while DC signals are blocked.

If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...
