← ScienceIn a distributed sensor network using resonant inductive coupling for wireless power transfer, which risk raises because antenna alignment degrades?
A)Increased medium access protocol collisions
B)Lower impedance matching efficiency✓
C)Enhanced time-division multiplex throughput
D)Reduced electromagnetic interference susceptibility
💡 Explanation
Degraded alignment reduces magnetic flux linkage via Faraday's law of induction, therefore lower impedance matching efficiency results, because the induced voltage is weakened leading to a power transfer mismatch rather than improved transfer, causing greater induced current or lower interference.
