Hello! Can anybody be kind to help me with the calculation of the resistors and the capacitors values? I want to drop the AC voltage from 230V to ca 40V and the maximum current will be at 40mA. Thanking you in advance! Regards =C5keN=20 -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
