← TechnologyWhich outcome occurs when impedance mismatches within long underground power cable circuits?
A)Reflected power wave generation✓
B)Increased dielectric breakdown strength
C)Harmonic current amplitude suppression
D)Reduced skin effect resistance
💡 Explanation
Reflected power waves occur because impedance mismatches create standing waves. The Transmission Line Effect causes signal reflection where impedance changes arise; therefore reducing transmitted power rather than improving cable strength because harmonic interference is not impacted by impedance matching here.
