Practical Electronics/Simplest Circuits

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 = $\frac{1}{C} \int I dt$	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 = $\frac{1}{L} \int V dt$	X = ωL/_90 = jωL = sL	Z = R + X = R + jωL
