← ScienceWhich outcome occurs when radio frequency identification (RFID) tag enters electromagnetic field of reader?
A)Tag antenna induces current to power chip✓
B)Transistor gate leakage causes memory wipe
C)Capacitor dielectric breakdown shorts circuit
D)Resistor thermal runaway disables modulation
💡 Explanation
When an RFID tag enters an electromagnetic field, the tag's antenna induces a current via electromagnetic induction, providing power to the integrated circuit. Therefore, the tag antenna induces current, rather than leakage, breakdown or runaway which require different electrical effects at other field conditions.
