Super Capacitors - Different Then Others (part 2)

Super Capacitors – Different Than Others (part 1)

Capacitors store electric charge. Because the charge is stored physically, with no chemical or phase changes taking place, the process is highly reversible and the discharge-charge cycle can be repeated over and over again, virtually without… Read more
