← ScienceWhich effect does increased inductance cause in transmission lines?
A)Slower wave propagation speed✓
B)Reduced characteristic impedance
C)Lower distributed capacitance
D)Minimal attenuation of signals
💡 Explanation
Increased inductance leads to a higher impedance, since impedance is proportional to the square root of inductance over capacitance, because group velocity decreases. Therefore, wave propagation speed slows, rather than being unaffected at minimal attenuation under different conditions.
