Final answer:
Electrolytic capacitors and oil-filled capacitors are typically connected in series during the starting process, accommodating the initial high inrush current by lowering total capacitance.
Step-by-step explanation:
During the starting, the electrolytic capacitor and the oil filled capacitor are connected in series. This is because when capacitors are connected in series, the total capacitance is lower than any of the individual capacitors' capacitances, which matches the requirement for the initial high inrush current when starting. Capacitors, such as the parallel-plate capacitor, consist of two plates of opposite charge separated by a dielectric. When initially uncharged capacitors are connected to a battery, they develop separated charges of +Q and -Q on their plates, creating an electric field between them that is proportional to the surface charge density.
During the starting phase of a single-phase induction motor, electrolytic capacitors and oil-filled capacitors are often used to create a phase shift between the start and run windings. These capacitors are connected in series with the start winding. The purpose of this configuration is to provide the necessary phase displacement between the currents in the start and run windings, enabling the motor to generate a rotating magnetic field and achieve sufficient starting torque.
The capacitors are connected in series with the start winding to introduce a phase shift in the current flowing through the winding. This helps create a rotating magnetic field, initiating the rotation of the motor during the starting process. The specific type of capacitor (electrolytic or oil-filled) and its capacitance value depend on the motor's design and requirements.
