← ScienceWhich behavior causes reduced impedance in coaxial cables containing dielectric spacers?
A)Increased capacitive reactance magnitude
B)Decreased capacitive reactance magnitude✓
C)Elevated surge impedance value
D)Amplified characteristic inductance value
💡 Explanation
Reduced impedance results as frequency increases because capacitive reactance decreases inversely due to the relationship Xc=1/(2πfC); therefore, impedance lowers rather than increases, due to a greater capacitive contribution and not amplified inductance.
