How does a start run capacitor work?

In this regard, what is the difference between a start and run capacitor?
The start capacitor creates a current to voltage lag in the separate start windings of the motor. The current builds up slowly, and the armature has an opportunity to begin rotating with the field of current. A run capacitor uses the charge in the dielectric to boost the current which provides power to the motor.
Furthermore, can I use a run capacitor in place of a start capacitor? According to me, if we use run capacitor as start capacitor, there won't be any problem. Yes, the starting characteristics may not up to the mark, motor may take higher starting current with lower torque.
Also to know, how do you connect a start and run capacitor?
How to Wire Up a Start Capacitor
- Turn off the electricity to the unit the motor operates.
- Inspect the start capacitor's wiring diagram.
- Push the wire terminal on the start capacitor relay's "Common" wire, usually the black wire, to the common terminal on the load side of the unit's contactor.
Why does a motor need a start capacitor?
With a capacitor connected in series to the secondary winding, the magnetic field it produces lags behind the magnetic field generated by the primary winding. This difference in phases creates a starting torque and the motor starts to rotate. Capacitors that allow a motor to start rotating are called start capacitors.
