What combines to create the self-resonance of a component?

  1. The component’s resistance and reactance
  2. The component’s nominal and parasitic reactanceRespuesta correcta
  3. The component’s inductance and capacitance
  4. The component’s electrical length and impedance

Explicación

Every real component has both the reactance it is meant to provide and an unwanted reactance of the opposite kind from its physical construction. Where those two are equal in magnitude the component resonates, which is its self-resonant frequency.
