Practical Electronics/Simplest Circuits

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 = ${\displaystyle {\frac {V}{R}}}$  0 Z = R
Capacitor C V = ${\displaystyle {\frac {1}{C}}\int Idt}$  I = ${\displaystyle C{\frac {dV}{dt}}}$  X = ${\displaystyle {\frac {1}{\omega C}}/_{-}90=}$ ${\displaystyle {\frac {1}{j\omega C}}}$  = ${\displaystyle {\frac {1}{sC}}}$  ${\displaystyle Z=R+X=R+{\frac {1}{j\omega C}}}$
Inductor L V = L ${\displaystyle {\frac {dI}{dt}}}$  I = ${\displaystyle {\frac {1}{L}}\int Vdt}$  X = ωL/_90 = jωL = sL ${\displaystyle Z=R+X=R+j\omega L}$

Series CircuitEdit

With three components R, L, C, connected in series we have the following circuits

Parallel CircuitEdit

With three components R, L, C, connected in parallel we have the following circuits
