實用電子學/並聯 RL

摘要

電路	符號	串聯	並聯
RL		一個並聯 RL 電路
阻抗	Z	$Z_{t}=R+\omega L$	$Z_{t}={\frac {\omega RL}{R+\omega L}}$
電壓	V	$V=IR+L{\frac {dI}{dt}}$	$I={\frac {V}{R}}+{\frac {1}{C}}\int Vdt$
電流	I	${\frac {dI}{dt}}=(V-IR){\frac {1}{L}}$	$\int Vdt=C(I-{\frac {V}{R}})$
相位角	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)${\frac {L}{R}}$
