← ScienceWhich outcome occurs when a power transformer's inductive reactance decreases?
A)Increased eddy current circulating in core✓
B)Reduced magnetic field strength in windings
C)Decreased voltage regulation under load
D)Higher capacitive discharge into grid
💡 Explanation
Decreased reactance increases current, thus increasing eddy currents due to electromagnetic induction within the transformer core, because the core more readily allows changing magnetic flux; therefore, eddy current losses rise, rather than voltage improving or capacitive effects increasing.
