A sensitive electronic medical device malfunctions due to nearby radio transmissions. Which mechanism explains why electromagnetic interference affects the device?

A)Capacitive reactance exceeds inductive reactance

B)Ground loop induces circulating current

C)Skin effect concentrates current on surface

D)Radiated energy induces voltages in conductors✓

💡 Explanation

Electromagnetic interference couples energy into the device via radiated energy inducing voltages in the internal conductors, because these act as antennas. Therefore, radiated coupling causes malfunction, rather than ground loops or skin effect, which are different mechanisms.
