Summarize this article for a 10 year old
A motor capacitor[1][2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field.[citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor).[2]
Motor capacitors are used with single-phase electric motors[3]:ā11ā that are in turn used to drive air conditioners, hot tub/jacuzzi spa pumps, powered gates, large fans or forced-air heat furnaces for example.[1] A "dual run capacitor" is used in some air conditioner compressor units, to boost both the fan and compressor motors.[1] Permanent-split capacitor (PSC) motors use a motor capacitor that is not disconnected from the motor.[4]
