Can capacitors in electrical circuits provide large-scale energy storage?
(Phys.org)—Capacitors are widely used in electrical circuits to store small amounts of energy, but have never been used for large-scale energy storage. Now researchers from Japan have shown that the right combination of resistors and capacitors can allo
