What shape is the capacitor

Capacitors

The current flowing in this circuit can be calculated using the definition of current, and the charge on the capacitor. Current is the rate of charge passing past a point, which is the same in this case as minus the rate of charge left on the capacitor - the capacitor losing charge corresponds to a positive current flowing from its positive plate to its negative plate.

Run Capacitor vs. Start Capacitor: What''s the Difference?

Ultimately, understanding the different functions of run and start capacitors can help prevent capacitor failure. Run capacitors are designed to stay on continuously, while start capacitors are only used for a short period of time when the motor is first turned on. If a start capacitor is left on for too long, it can overheat and fail.
