How do you identify a start capacitor?

A start capacitor can be identified by its physical characteristics and markings. It is typically cylindrical or oval in shape and may have a higher capacitance value (usually expressed in microfarads) than run capacitors. Additionally, it often has a voltage rating printed on its casing, which is usually lower than that of run capacitors. Furthermore, start capacitors are often found in applications like motors, where they are used to provide an initial boost of energy to start the motor.
