I am planning on building a small tesla coil out of a car ignition coil.
Because the coil won't 
be able to handle a large amount of power (my guess is between 50 and 100
watts), I will need to 
limit the current going in. I have measured the resistance of the primary,
which is 20 ohms. 
Therefor, at 240v it would draw 12 amps, using ohms law. If I wanted to
limit it to say 60 watts, 
I would need to limit it to 0.25 amps. 240/0.25 = 960 ohms, so I assume
that I would put a 1k, 
60w resistor in series with the primary. Would this work, or have I got
this totally wrong? 

Thanks,
Ben
