← ScienceWhich mechanism causes arc flash events in electrical panels?
A)Accelerated electromagnetic induction of plasma✓
B)Capacitive discharge between conductors
C)Increased dielectric breakdown strength
D)Magnetic field driven Lorentz constriction
💡 Explanation
Arc flash occurs due to accelerated electromagnetic induction of plasma, forming a conductive path, because ionized air markedly lowers resistance, allowing enormous current flow; therefore, arc flashes propagate, rather than being contained by standard fuse actions in overload.
