A vintage variable capacitor, or a mini sculpture? Either way, this thing looks so cool. It was once very functional, and still is, but we think it makes a great desk object! It also has a tactile turning feature, making it a desktop staple actually.
How it works: A capacitor is made from two conductors separated by an insulator. In this case, the conductors are metal plates, and the insulator is the air between the plates. Turning the shaft of the capacitor changes how much the metal plates overlap, changing the capacitance. (Capacitance is a measure of the capacitor’s ability to store electric charge.) These are commonly used in radios to tune the station.
