← ScienceWhich outcome occurs when parasitic capacitance shorts transformer windings?
A)Resonance leads to current surges✓
B)Reluctance causes increased core saturation
C)Eddy currents minimize energy dissipation
D)Hysteresis loss decreases magnetic coercivity
💡 Explanation
When parasitic capacitance forms a resonant circuit, there is high-frequency oscillation. This is due to **LC resonance**, which generates significant currents that can damage circuits because impedance drops sharply at the resonant frequency, therefore voltage remains fixed rather than dropping.
