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.

[James] designed a set of circuit boards that enabled him to place different types of capacitors at various distances along a set of PCB traces.

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.
