← TechnologyWhich outcome occurs within an aircraft's electrical circuit when impedance decreases sharply?
A)Arc flash incident risk increases✓
B)Transformer core saturation is likely
C)Harmonic distortion significantly reduces
D)Power factor approaches unity rapidly
💡 Explanation
An arc flash increase results because inrush current is high, following Ohm's Law. The mechanism of *fault current* causes rapid energy release. Therefore, arc flash probability increases, rather than core saturation or a reduction in harmonic frequencies if the protection clears quickly enough.
