How Capacitors Work
How Capacitors Work. I like to answer the question of "How does a capacitor work?" by saying that a capacitor works like a tiny rechargeable battery with very low capacity. But a capacitor is usually charged and discharged in a fraction of a second. So it''s not used for the same purpose as a battery.
How Capacitive Pressure Sensor Works
Each plate forms a capacitor with the sensing diaphragm, which is connected electrically to the metallic body transducer.
