i have a blown resistor on a pcb its either 68R 3watts or 68K 3watts.
It drops the voltage from 230v to 200v ac its then converted to dc via the diodes. can anyone help by giving me the formula to workout the correct size for the resistorhttp://forum.allaboutcircuits.com/images/smilies/confused.gif
