R.L,C Components[edit]

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 + j\omega L
