← ScienceWhich risk increases when high impedance connects toroidal transformer windings?
A)Increased core saturation and overheating✓
B)Reduced eddy current losses overall
C)Enhanced magnetic field confinement
D)Improved voltage regulation instantly
💡 Explanation
High winding impedance limits current flow, reducing the transformer's magnetizing inductance therefore causing core saturation and increased hysteresis losses rather than regulating voltage as intended, because energy dissipates as heat in the core.
