← ScienceWhich outcome occurs when resonant frequency increases in a capacitive power transfer system?
A)Reduced energy transfer efficiency✓
B)Increased electromagnetic interference
C)Higher voltage stress on capacitors
D)Decreased reactive power demand
💡 Explanation
When resonant frequency increases, impedance mismatch occurs because inductive and capacitive reactances are not perfectly balanced at the higher frequency reducing the power transfer due to less effective coupling. Therefore reduced energy transfer efficiency result, rather than changes to interference, capacitor voltage, or reactive power profiles which require near-perfect frequency matching.
