← ScienceWhich consequence results when an inductor's insulation fails under fast switching?
A)Reduced electromagnetic interference emission
B)Increased device energy efficiency
C)Higher peak transient voltages form✓
D)Decreased core saturation risk
💡 Explanation
When insulation within an inductor breaks down under rapid voltage changes, parasitic capacitance discharges suddenly via dielectric breakdown; therefore, high-frequency oscillations amplify, creating large voltage overshoots, rather than smooth voltage transitions.
