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. Televisions use a large number of ...

Capacitor discharge circuits are used extensively in fast pulse generation. In such applications, the capacitor's stray inductance (or equivalent series inductance ...

Using supercapacitors (also known as ultracapacitors, supercaps, etc.) to replace batteries in portable micropower applications is gaining momentum. Here's some ideas on how to get going with "green ...
