Series RLC impedance: 62830.34 Ohm at 89.9 deg

  • The positive phase angle (89.9 deg) shows the circuit is net inductive: the inductor's reactance dominates and current lags voltage.
  • The driving frequency (1000000.0 Hz) is 19769.2% above the resonant frequency (5032.92 Hz).
  • A Q factor of 3.16 indicates moderate selectivity with a bandwidth of 1591.55 Hz.
  • Inductive reactance X_L = 62831.85 Ohm, capacitive reactance X_C = 1.59 Ohm at this frequency.

Next stepFor a series RLC circuit, minimum impedance occurs at resonance. Tune L or C so that f0 equals your driving frequency to maximise current.
