Industry HOW DOES CAPACITOR TYPE FAN REGULATOR WORK? | Capacitor Connect
It may be noted that when making combinations of capacitors, a capacitor previously charged in one step gets discharged into the new capacitor being added, which is a short-circuit path for the charged capacitor. Hence its discharge current needs to be controlled for the safety of both capacitors. Often, a 4-speed regulator is used.

Industry WHY DOES NOT CAPACITOR ALLOW DIRECT CURRENT TO
Introduction:A capacitor is a passive electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material called a dielectric. When a voltage is applied across the plates, the capacitor charges up and stores energy. However, a capacitor does not allow direct current (DC) to flow through it.
