Both AC and DC describe types of current flow in a circuit. Most homes are wired for AC , so if you plan to connect your Tardis music box project to an outlet, you will need to convert AC to DC. Everything that runs off of a battery, plugs in to the wall with an AC adapter, or uses a USB cable for power relies on DC. Such power supplies will employ a transformer to convert the input voltage to a higher or lower AC voltage. A rectifier is used to convert the transformer output voltage to a varying DC voltage, which in turn is . Alternating current ( AC ) is an electric current which periodically reverses direction, in contrast to direct current ( DC ) which flows only in one direction.
Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they .
