Demountable Transformer - 10 Kv Arc
To demonstrate that a large voltage increase is attainable using a transformer.
Letbold demountable transformer core with 250 turn primary and 23,000 turn secondary, secondary electrodes.
The primary coil is plugged into 110 VAC. The turn ratio of nearly 100 produces a large secondary voltage which arcs across electrodes placed on the output of the secondary coil.
