Types of Power supply
Power supply per se is not a singular term. It represents a phenomenon that explains how electricity flows and is made usable.
Electricity or power flows in two ways: AC and DC. AC stands for Alternating Current. DC is the full form of Direct Current. Both represent the flow of electrons through the conductor. However, they differ because in each case the direction of flow differs. While the DC flows in a single tract in a steady manner, AC switches directions as it flows along the conductor.
Accordingly, AC is used to supply power in long distances to the numerous power companies. These are high voltage currents received by transformers of power companies. On the other hand, DC power supplies are utilised to transmit electricity/power to households on a small scale.
In so many words, DC power supplies are indispensable and omnipresent components used in households all over the world. These supplies are vital to provide electricity to almost each portage electronic gadget you can lay your hands on. Right from your home computer, to cellular phones, MP3 players and car audio equipment; every device uses DC power supply to be usable.
