Their job is to convert high-voltage alternating current from the mains into low-voltage direct current for mobile phones, laptops, iPods and other electronic gadgets.

ECONOMIST: How a boring gadget saved $2 billion-worth of electricity

Large-scale electricity transmission usually uses alternating current, in which both current and voltage oscillate.

ECONOMIST: Superconductors are starting to become useful

For example, a system could be injected with current and voltage to see how it would react.
