Copper is the most widely used electrical conductor in electronics, but there's a contender less spoken of: silver. Despite being the best conductor, its high cost restricts use to specialized equipment, like satellites and high-end audio gear. Intriguingly, if silver oxidizes, it still conducts electricity, contrary to copper oxide which stops conduction. Just imagine, world-changing tech could hinge not on fancy gadgets but on the humble refinement of materials. Got a cool electronics fact or insight? Enlighten us with your response!
