Notes

[1] These measurements only apply to a single line. Where a double line is employed the capacity is halved.

[4] In wireless telegraphy "arcing" is principally caused by the continuation of the supply current in the spark-gap after the capacity has been charged to a potential sufficient to break down the insulation of the gap.
