Impedance | Z | $Z_{t}=R+\omega L$ | $Z_{t}={\frac {\omega RL}{R+\omega L}}$ |

Voltage | V | $V=IR+L{\frac {dI}{dt}}$ | $I={\frac {V}{R}}+{\frac {1}{C}}\int Vdt$ |

Current | I | ${\frac {dI}{dt}}=(V-IR){\frac {1}{L}}$ | $\int Vdt=C(I-{\frac {V}{R}})$ |

Phase Angle | I | tan θ = $\omega {\frac {L}{R}}$ = 2πf ${\frac {L}{R}}$ f = (Tanθ/2π)${\frac {R}{L}}$ t = (2π/Tanθ)${\frac {L}{R}}$ |
tan θ = $\omega {\frac {L}{R}}$ = 2πf ${\frac {L}{R}}$ f = (Tanθ/2π)${\frac {R}{L}}$ t = (2π/Tanθ)${\frac {L}{R}}$ |
