Tesla’s Fig. 1 is a complete high-frequency lighting system. A comparatively low-EMF alternating source G feeds an induction coil P/S. Its secondary charges condenser C. The condenser then disruptively discharges through circuit A and air gap a, including primary P′. Long fine-wire secondary S′ produces the very-high-potential output used for lighting.
Accuracy rule: this exhibit is not a generic modern Tesla coil. Every major stage corresponds to a labeled part of Fig. 1 and the written specification.
Tesla begins Fig. 1 with G, an alternating-current generator of comparatively low electromotive force.
