How do you know if a solid capacitor is bad?

How do you know if a solid capacitor is bad?

To my knowledge the only visible hints as to a bad cap are, of course, leakage and/or swelling. Seen a number of caps some years back that had really domed tops. The term ‘solid state caps’ is a misnomer. They still have electrolyte in them, just not in liquid form.

What is J in capacitor impedance?

The J operator The impedance of a coil is not real but imaginary. In a coil, the voltage always runs 90° ahead of the current, this is indicated by +J followed by the impedance value. A capacitor is also a imaginary impedance.
