← ScienceWhich outcome occurs when high-frequency resonant inductive coupling charges a shielded implantable medical device?
A)Capacitance increases, interfering with telemetry✓
B)Inductance decreases due to eddy currents
C)Electromagnetic shielding eliminates energy transfer
D)Skin effect causes overheating of tissues
💡 Explanation
Capacitive coupling increases because the shield creates parasitic capacitance when exposed to changing fields; therefore, telemetry signal integrity worsens; rather than being blocked, energy transfer couples capacitively causing interference due to detuning of resonance.
