I am planning to built a circuit with 3 polypropylene film 3900 pF 5% 3 kV DC radial capacitors connected in series. Before I start this, I want to make sure the capacitors are safely discharged. I am also thinking that I will need to safely discharge them after they are soldered together. I tried researching this and found a site on Digikey to calculate what size resistor should be used, but found that it would allow any ohm value based on time:
What would be an appropriate resistor for safety discharging these capacitors? I am not concerned if it takes a while for it to discharge, I just want to make sure I do not choose one that is to small for capacitors of this size.
