What is POWER SUPPLY? What does POWER SUPPLY mean? POWER SUPPLY meaning, definition & explanation

                                  

a power supply is an device that supplies electric energy to an electrical load the first function of an influence supply is to convert one sort of electricity to a different end as a result power supplies are sometimes mentioned as electrical power converters some power supplies are discrete standalone devices whereas others are built into larger devices along side their loads samples of the latter include power supplies found in desktop computers and consumer electronics devices every power supply must obtain the energy it supplies to its load also as any energy
