If it was a "wet" capacitor with a gel / liquid electrolyte, that was likely either ethylene glycol (aka "anti-freeze") or boric acid (think Borax laundry soap). If it was a solid capacitor, the equivalent of an electrolyte was another film of manganese dioxide (MnO2). Wet caps usually pop, but not smoke.
Get PriceNote: If your capacitor doesn''t come with a cover, you can keep it that way! Reason 4 of 4: Problems With The Motor. If you''ve checked all other options but the capacitor keeps blowing, the motor might be at fault. The motor might be damaged due to working too much to keep the capacitor going. In that case, it has to be replaced. Solution
Get Price$begingroup$ If we overlook the capacitor plate degradation for a moment, it''s not like putting a 30 ohm resistor across the line, at least not in one sense. I would indeed pass ~7.7 A and the apparent power would be ~1.8 kW but most of that is reactive power and would be lost in the power company''s equipment.
