← ScienceWhich outcome results during a lightning strike near an ungrounded radio antenna array when the atmospheric electric field collapses?
A)Electrostatic discharge induces antenna ringing✓
B)Reduced atmospheric refraction bending waves
C)Increased signal-to-noise electromagnetic ratio figures
D)Dielectric breakdown of nearby insulators
💡 Explanation
Electrostatic induction occurs because collapsing fields generate voltage spikes, creating transient oscillations within the antenna elements. Therefore, electrostatic discharge ringing happens, rather than altered wave refraction or insulator faults produced under longer duration potential stresses.
