Resonance is a very real phoenomenon & is a huge part of Tesla-type inductor devices.
Otherwise all you're doing is brute forcing the electrons into oscillation, rather than using their natural frequency.
Exactly like breaking a glass, you must match the natural note that the glass rings at, then just SIMPLY raise the volume.
At resonance, the electrons require less power to do more work.
