← ScienceWhich mechanism allows a wireless power transfer system to efficiently transmit energy via inductive fields across a distance?
A)Resonant inductive coupling adjusting impedance✓
B)Capacitive discharge using electrodes spacing
C)Direct conduction with shared ground path
D)Faraday shielding blocking field leakage
💡 Explanation
When the system components are designed to resonate at the same high frequency, resonant inductive coupling maximizes energy transfer due to impedance matching which minimizes reflected power. Therefore resonant inductive coupling results in an ideal scenario by adjusting impedance, rather than relying on capacitive electrodes, conductive circuits, or shielding leakage.
