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
High-voltage DC can carry power over long distances at lower cost than alternating current, but the transformers still cost too much to make the idea widespread.
