Jargon buster

Plain-language definitions for the technical terms used above.

DC
DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
rectifier diode
A diode designed to let current flow mainly in one direction, often used to convert AC into DC or to protect circuits from reverse current. It matters because rectifier diodes are chosen for power handling rather than fast signal switching.
