Introduction
Together with engeneering student Mathias Neerup we have built a working spark gap tesla coil. The first system was a small 32mm coil, but that quickly evolved into the 50mm system displayed here.
SGTC
Specifications
| Power supply | variable power supply 0-30VDC 8A |
| MMC bank | 3 parallel strings with 6 capacitors in each. FKP capacitor 47nF 2000v for a total of 23,5nF and 12kV |

Urgent! What is the value of resistance at the top of the capacitors ??
Are you asking for the resistance across the capacitors?
Yeah. How many ohms?
there is a 1m ohm bleed resistor across each of the capacitors.
1 m ohms instead of 10 megohms olurmu. How many V / W?
