Dual Run Capacitor – Everything You Need to Know
A dual run capacitor helps your AC''s compressor and condenser fan motor turn on. If your dual run capacitor goes bad, then one or both of these components won''t turn on. A dual run capacitor is actually two capacitors combined into a single package – one capacitor is for your compressor, and the other is for your condenser fan motor.

How to clean my tuning capacitor? | Electronics Forums
drastically due to WD40 which may have spilled on the capacitor plates. So, I tried measuring the resistance of some WD40 on the table and it measured over 20Megs (limit of the meter). A few hours later, the cap started working again, so I connected a 10 Meg resistor across the antenna capacitor plates which made very little difference. So,
Variable Capacitor : Construction, Types and Their Applications
The applications of the variable capacitor include the following. Trimmer capacitors are used where a capacitance value is needed to be matched to a particular circuit in the manufacturing process. The main reason to use this capacitor is, the components used in the circuit have own tolerances. So the tolerance values can be changed by 20% ; from what the designer expected …
