Where can I learn more about capacitors?
One of the things that still baffle me today is when to use and how to select the correct capacitor.
I've read through this chapter about capacitors: http://www.allaboutcircuits.com/vol_1/chpt_13/index.html
Afterwards I feel I undestand how they work, but still don't have the two most basic questions answered:
- When do you need to add use a capacitor? (signal smoothing, power storage)
- How do you select the correct capacitor? (how many Farads should it be for my application?)
Can somebody point me to a good explanation or resource online? Maybe somebody could write a blog entry or walkthrough about this.
