Title: capasistor calculations
Post by: BANE on April 05, 2008, 06:37:32 PM
Hello, does anybody have a website handle for learning about math equations for capasistance in general circuits?  I kind of know how there used but not what type of farads or voltage to use.

uhm... wikipedia? http://en.wikipedia.org/wiki/Capacitance

You also can pick up an intro electronics book.  Most of them have a chapter for capacitors in the beginning, and they usually have enough information for most circuits.

corrections first

its capacitors and capacitance

and abt the calculations look at the wikipedia link it will give u a good overview of the subject

yep

what exactly are you looking for ?

charging time of capacitor , etc. ?

what i'm looking at trying is to make manual servo controller like this one just for the heck of it

I just wanted to know how they got some of there capasistor values
