This resistor will dissipate exactly 0.3W. Choose your wattage the way you see fit![Icon_smile Icon_smile](https://philcoradio.com/phorum/images/smilies/icon_smile.gif)
The Voltage at the top of the divider is about 250V.
The 32K resistor will drop 97.5V.
The dissipated wattage is U-square / R = (97.5*97.5)/32,000=0.29 W
