The most widely used electronic component is the Capacitor. The capacitor is a passive circuit element but it doesn''t absorb electric energy rather it stores energy.

By David L. Chandle, Massachusetts Institute of Technology October 4, 2023. MIT engineers have created a "supercapacitor" made of ancient, abundant materials, that can store large amounts of energy.
