← ScienceWhich outcome occurs when a cable's insulation degrades increasing capacitance?
A)Signal reflections increase along cable
B)Characteristic impedance of cable decreases✓
C)Electromagnetic Interference (EMI) decreases
D)Transmission line inductance correspondingly increases
💡 Explanation
Increased capacitance reduces the cable's impedance because impedance is inversely proportional to the reactive capacitive element called capacitive reactance. Therefore, the characteristic impedance will decrease rather than EMI reduction or increased reflections from mismatched impedances.
