A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
Yes, it is an adjustable capacitor. Each capacitor ''plate'' is usually a stack of vanes, with a gap between each vane. A vane looks like slightly less than half a disc, mounted on the central shaft. One ''plate'' stack is fixed, the other is rotated by the adjustment shaft. This moves the stacks of vanes in between each other.
