← ScienceWhich effect occurs when mismatched impedance attenuates transmission?
A)Signal reflection increases sharply✓
B)Resonance frequency drifts downward
C)Ohmic losses dominate power dissipation
D)Dielectric breakdown intensifies rapidly
💡 Explanation
Signal reflection increases because impedance mismatch prevents efficient power transfer; wave energy is reflected at the discontinuity through the standing wave ratio mechanism, rather than transmitted. Therefore, reflection increases, rather than dissipation or breakdown at resonance.
