← ScienceWhich outcome occurs when a cable's insulation degrades near a high-frequency power inverter, increasing capacitance?
A)Increased electromagnetic interference generation✓
B)Decreased inverter switching frequency
C)Reduced cable current-carrying capacity
D)Improved inverter efficiency at harmonics
💡 Explanation
Increased capacitance allows greater displacement current flow, and therefore increased electromagnetic interference generation due to parasitic coupling. This occurs because of increased capacitive reactance; therefore EMI worsens, rather than a change elsewhere inside the circuit.
