Capacitors 218

Capacitors are components of electrical and electronics that store electric charge. They are mostly used in smoothing, filtering and timing circuits. They smooth circuits because they store charge, they filter circuits because they allow a.c and block d.c and finally they are used to time since a capacitor takes up […]
