thanks for helping me in this subject. now I am going deep how to calculate the need capacitors for rectifying. :-) Regards Tal Bejerano AMC - ISRAEL -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of Bob Ammerman Sent: Wednesday, May 29, 2002 8:01 PM To: PICLIST@MITVMA.MIT.EDU Subject: Re: Dual Voltage help Both are correct.
