The bigger the resistor the faster it will bleed down a cap.
In terms of resistance, the opposite is true. The smaller the resistor value, the faster the cap will discharge through it. In terms of physical size, which has mostly to do with power handling, it only matters that the resistor is big enough that it won't overheat during the discharge process. A 10K ohm 1W or 2W is typically what I use.
That's what i get for posting way too early in the morning. Intended meaning was the higher the rated wattage not the larger the resistance.
220k is definitely overkill for just about any cap. Was a combination of what I had on hand and the fact that I needed to bleed some huge caps. Will work will just discharge slower. Still generally talking about seconds.
If I remember correctly the actual formula for bleeders is R = t(in sec) / ( 5 * C ). Someone please correct me if I am wrong.
