← ScienceWhich outcome increases when operating a high-voltage transformer at 500 kHz, exceeding its designed resonant frequency?
A)Core saturation and energy loss✓
B)Increased capacitive energy storage
C)Optimal energy transfer efficiency
D)Decreased skin effect energy waste
💡 Explanation
Core saturation and energy loss occur because, at 500 kHz, the **increasing-hysteresis losses** prevent complete magnetic domain alignment in the core. Therefore, excess energy dissipates as heat, rather than efficient magnetic field propagation, leading to saturation rather than efficient transfer.
