Impedance is minimal on resonance
Evidence
On resonance, the forced mass responds with its largest velocity ν0 for a given force F0, so the impedance Z = F0/ν0 is a minimum on resonance. Since very often it is impedance and not power that is measured, it helps to plot the admittance A = 1/Z, which maximizes when the impedance has a minimum. — Eric J.
