R.L,C ComponentsEdit

Below is the summary of the three components R , L , and C

Components	Symbol	Voltage V	Current I	Reactance X	Impedance Z
Resistor	R	V = IR	I = ${\frac {V}{R}}$${\frac {V}{R}}$	0	Z = R
Capacitor	C	V = ${\frac {1}{C}}\int Idt$${\frac {1}{C}}\int Idt$	I = $C{\frac {dV}{dt}}$$C{\frac {dV}{dt}}$	X = ${\frac {1}{\omega C}}/_{-}90=$${\frac {1}{\omega C}}/_{-}90=$${\frac {1}{j\omega C}}$${\frac {1}{j\omega C}}$ = ${\frac {1}{sC}}$${\frac {1}{sC}}$	$Z=R+X=R+{\frac {1}{j\omega C}}$$Z=R+X=R+{\frac {1}{j\omega C}}$
Inductor	L	V = L ${\frac {dI}{dt}}$${\frac {dI}{dt}}$	I = ${\frac {1}{L}}\int Vdt$${\frac {1}{L}}\int Vdt$	X = ωL/_90 = jωL = sL	$Z=R+X=R+j\omega L$$Z=R+X=R+j\omega L$
