A Power Socket is a Device to Which Electrical Devices Can Be Connected to Receive the Electric Current Required For Their Operation. Connected by a System of Cables to a Power Source, Usually, an Electricity Generation Facility operated by an energy Production company, generally has no moving parts. Instead, it contains metal strips that make contact with the prongs of an Electric plug inserted into the socket. It is Through these Contacts That the Electric current is Transmitted. Electrical Devices that connect to a Power Source Through a Power Socket are Considered to be Portable Because they can easily be Connected and Disconnected From the Power Source.

A Fan Speed Controller Controls The Voltage Across the Fan and Therefore Indirectly Controls its speed 220v AC line. A ceiling Fan Speed Regulator Actually Measures and Regulates the Speed of the Fan Using its Tachometer. Fan Speed is Controlled with Thyristor or Transformer Speed Controllers for Ceiling fans, and table fans. the fan is Controlled by a Capacitor, and the Voltage across the fan Determines the fan speed. A Speed Control loop Can be Implemented That is Independent of Manufacturing Variances and Wear on The Fan control system.

CFL stands for Compact Fluorescent Lamp which is an improved version of tube lights of earlier days. Like tube lights, it is a vacuum glass tube with fluorescent powder coating which is not as long and straight as tube lights but curved/twisted compact, or small in size. Like a tube light, it has electrodes or filaments at both ends. But in this case, instead of a choke, there is an electronic circuit that drives the Compact Fluorescent Lamp. Because the red wave is less in the light of the Tubelight and Compact Fluorescent Lamp, the object looks a little pale or the correct color of the object does not appear.
