← TechnologyWhich undesirable effect results when an electrical grid experiences localized over-demand?
A)Voltage sags and brownouts occur✓
B)Harmonic distortion gets amplified
C)Frequency cascading resonance develops
D)Insulation breakdown risk increases rapidly
💡 Explanation
Voltage sags happen because increased current draw through the grid's impedance causes a voltage drop; therefore, localized power demand triggers voltage drop rather than amplified interference or material failures under brief overload, though that could also happen given a different initial cause.
