[TCML] Bleeding resistors for MMC



I have 10 Mohm 1/2W resistors on all my 0.1 uF 3kV caps for bleed, and they have all functioned very well, nothing blowing up.    Got them from TeslaStuff (rainylk) on ebay.

Now that I am thinking about it, I suppose you could do this: 

           3000 V / 10,000,000 ohm = 0.0003 A
           3000 V * 0.0003 A = 0.9 Watt  

Example if I have 7 x 3000V caps that's 21,000V, but hopefully it would never go that high, so will be less than max volts per cap, so it's more like

           2000 V / 10,000,000 ohm = 0.0002 A
           2000 V * 0.0002 A = 0.4 Watt

which us less than 1/2 Watt.    

Possibly AC calculations would be closer.
