Assertion: capacitor's esr | /r/CapableOf | vary with frequency
Facets:
value: due to the skin effect
type: CAUSE
Source sentences:
text: The ESR varies with frequency due to the skin effect, as well as other effects related to the dielectric characteristics.
text: When precision is required, measurements must be taken under appropriately specified conditions, because ESR varies with frequency, applied voltage, and temperature.
