Which 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.
