Extra exam question E6D06
Subelement E6, CIRCUIT COMPONENTS· Group E6D
What core material property determines the inductance of an inductor?
- A.Permittivity
- B.Resistance
- C.Reactivity
- D.Permeability (correct answer)
WhyThe core material property that determines an inductor's inductance is permeability. An inductor's core material determines its inductance chiefly through the core's permeability, its ability to concentrate and support magnetic flux compared to air, answer D. Permittivity relates to electric fields and capacitors, not magnetic cores, and resistance and "reactivity" (not a standard term) don't describe the relevant core property either.
