Capacitor in Electronics – What It Is and What It Does
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.

Tesla Coil Design, Construction and Operation Guide
The spark gap is used as a switch to momentarily connect the primary capacitor to the primary coil. When the gap is shorted the cap is allowed to discharge into the coil. Many spark gap designs can be used. Spark gaps come in two basic designs: static and rotary. When the gap electrodes are stationary, the gap is referred to as a "static" gap.
electrolytic capacitor
Some are single coils that reverse polarity to open and close a directional turn. Other coils are "twin-coil", one coil pulls the track to one side and the other pulls it back to the original position. Going from a current controlled device like the Darlington to a voltage controlled device like an FET requires a change in the circuit.
