What letter is commonly used to represent susceptance?
The correct answer is D: B. What letter is commonly used to represent susceptance is B. Susceptance is represented by the letter B. For amateur radio operators, this is important for circuit theory. Understanding this helps when working with admittance.
Exam Tip
Letter for susceptance = B. Think 'S'usceptance = 'B'. Susceptance is represented by the letter B. Not G (conductance), not X (reactance), not Y (admittance) - just B.
Memory Aid
"Letter for susceptance = B. Think 'S'usceptance = 'B'. Susceptance is represented by the letter B. Important for circuit theory."
Real-World Application
Susceptance: It's commonly represented by the letter B. Susceptance is the imaginary part of admittance (Y = G + jB). This is the letter - B represents susceptance.
Key Concepts
Why Other Options Are Wrong
Option A (G): Incorrect. G represents conductance, not susceptance - B represents susceptance. G is conductance.
Option B (X): Incorrect. X represents reactance, not susceptance - B represents susceptance. X is reactance.
Option C (Y): Incorrect. Y represents admittance, not susceptance - B represents susceptance. Y is admittance.
