Q:What’s the capacitor?
A:Capacitor is a two-terminal passive component used in electronic circuits. The basic construction consists of two plates of a conductor and a dielectric insulator between them.
The two ends of the capacitor are connected to alternating current, and the two ends of the capacitor respectively accommodate positive and negative charges. At this time, the current direction changes (alternating current), the metal sheet of the previous positive charge starts to discharge, and the negatively charged metal piece also has the same, until it is finished, it continues to change. Charging, when the metal strip with positive and negative charges is now, the charge is reversed, so cycle.
