Careful! The transformer will give (about) 15000 volts OPEN CIRCUIT
VOLTAGE and (about) 60 ma SHORT-CIRCUIT CURRENT. It most definitely
will not give 60 ma at 15 kV into a resistive load. If the load has
capacitive reactance it is possible to get a lot more power output ()and
destructive open-circuit voltage), as most coilers experience.
