No, that's a "choke", or if there are two coils, it's a transformer A capacitor is two "plates" (in reality they are usually just foil) that are connected to two wires. Often (typically) there is an electrolytic between the plates There is more to a capacitor, but that's the basics.
The secondary (or secondary coil) is a cone-shaped coil. Voltage to very high levels. The high voltage thus produced is given off by the ball terminal (G).
Following explanation of Tesla Coil operation refers to this diagram. Coils of copper wire. The iron core becomes an electromagnet.
Current changes the polarity of the electromagnet.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
