Is a Tesla pancake coil essentially the same as a Tesla coil with the windings in a flat spiral instead of in a helix, i.e. there's a primary coil of a just a few turns of thicker wire, and a secondary that's several hundred to several thousand turns of small wire (with one end grounded and the other attached to a circular or toroidal capacitor)?
