سؤال 273

What parasitic characteristic creates an inductor’s self-resonance?

  1. Skin effect
  2. Dielectric loss
  3. Coupling
  4. Inter-turn capacitanceپاسخ درست

توضیح

Adjacent turns of an inductor's winding are separated by a thin layer of insulation and act as small capacitors. This distributed inter-turn capacitance appears in parallel with the inductance and resonates with it, setting the coil's self-resonant frequency.
