Data record instr.vlf-test-set.why-low-frequency

Verified 2026-10-27 Confidence: Medium

The charging current of a capacitive load is proportional to frequency, so at a very low frequency the current and power needed to raise a long cable to test voltage are a small fraction of what a power-frequency set would need, which allows a VLF set to be small enough to carry.
