← TechnologyWhich outcome occurs when resonant inductive coupling allows wireless power transfer between loosely coupled circuits?
A)Increased sensitivity to foreign-object debris
B)Reduced circuit impedance matching sensitivity✓
C)Higher dependence on coil temperature stability
D)Decreased power source electromagnetic hardening
💡 Explanation
Loosely coupled resonant inductive coupling mitigates sensitivity because impedance matching uses reactive components' compensation rather than relying on tight coil proximity; therefore B is correct, rather than increased FOD sensitivity due to field disturbance.
