power adapter - Computer Definition. A power supply for electronic devices. Also called an AC adapter or charger, power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop. The additional DC voltages are created by internal circuits.
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.Electromagnetic induction produces an electromotive force across a conductor which is exposed to time varying magnetic fields.ommonly, transformers are used to increase or decrease the voltages of alternating current in electric power applications. A varying current in the transformer's primary winding creates a varying magnetic flux in the transformer core and a varying magnetic field impinging on the transformer's secondary winding.
