← ScienceWhich outcome occurs when a thermoelectric generator experiences overheating?
A)Reduced electrical power output✓
B)Increased Seebeck coefficient stability
C)Improved thermal energy conversion
D)Enhanced material stress resistance
💡 Explanation
Overheating a thermoelectric generator reduces power output because increased temperature elevates carrier concentration that favors a rise in internal resistance, through increased phonon-electron scattering. Therefore, power output decreases, rather than resistance stabilizing or rising beyond functional threshold.
