Practical Electronics/Circuits Analysis

Circuit Analysis

The resistors and inductors were both using the same formula when they are connected in the circuits See: Parallel and Series Connection

R.L,C Components

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

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