Which 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.
