How does one calculate the charge time of an RC circuit? I know the voltage, the capacitor value and the resistor value ofcourse. I am sure it does differ with the temprature also, but for now I am assuming room temprature. It would be nice to know how the temprature effects (by formula) the charge time also. Any help is appriciated. -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
