What combines to create the self-resonance of a component?
The correct answer is B: The component's nominal and parasitic reactance. What combines to create the self-resonance of a component is the component's nominal and parasitic reactance. Self-resonance occurs when nominal reactance interacts with parasitic reactance. For amateur radio operators, this is important for understanding component behavior. Understanding this helps when working with components.
Exam Tip
Self-resonance of component = nominal and parasitic reactance combine. Think 'S'elf-'R'esonance = 'N'ominal + 'P'arasitic reactance. Self-resonance occurs when nominal reactance interacts with parasitic reactance. Not resistance/reactance, not inductance/capacitance, not length/impedance - just nominal and parasitic reactance.
Memory Aid

Real-World Application
The self-resonance of a component: It's created by the combination of the component's nominal and parasitic reactance. For example, an inductor's nominal inductance interacts with its parasitic inter-turn capacitance to create self-resonance. This is the combination - nominal and parasitic reactance.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. Component's resistance and reactance isn't what creates self-resonance - nominal and parasitic reactance is. Resistance/reactance isn't the combination.
Option C: Incorrect. Component's inductance and capacitance isn't specific enough - nominal and parasitic reactance is. Inductance/capacitance isn't specific.
Option D: Incorrect. Component's electrical length and impedance isn't what creates self-resonance - nominal and parasitic reactance is. Electrical length/impedance isn't the combination.
