How the Machine Builds Its Charge
The two discs turn in opposite directions. Metal sectors on each disc take on charge by induction from the sectors passing on the other disc, and each revolution adds to the separation, so positive charge gathers at one terminal and negative charge at the other. Once the potential difference is large enough, the air between the terminals ionises and a spark crosses; in dry air the gap can be up to 75 mm.
Getting Good Sparks
Moisture and dust let charge leak away across the disc surfaces, so the machine gives its longest sparks in a dry room with clean, dry discs. Its current is small, at most 7 µA even with the terminals shorted, so it gives a high voltage but very little charge per second. Bring the terminals together to discharge them after use.
