A tesla coils secondary coil is where all of
the voltage multiplication is acheived.
Essentially the secondary coil is a single air cored inductor wound with 500-2500 turns of insulated wire.
Essentially the secondary coil is a single air cored inductor wound with 500-2500 turns of insulated wire.
The wire size and turns are usually dictated
by the required size of the secondary.
The secondary is wound onto an insulating
former, usually PVC, but many other formers are used including cardboard, glass
& polypropylene.
To help insulate and to prevent corona
discharge the secondary is coated with many layers of varnish, ideally
until its has a smooth finish.
