+We will indicate the amplitude and phase relationship through the use
+of complex notation: a complex number is used to indicate only the
+amplitude and phase of voltages and currents in the circuit (since the
+sinusoidal time variation factor is common to all terms).  For
+example, a circuit described by the equation
+\[
+i(t)=I_{0}\cos(\omega t+\theta)
+\]
+can be written in complex exponential form as
+\[
+i(t)=\Re\{I_{0}e^{j(\omega t+\theta)}\}=
+\Re\{I_{0}e^{j\theta}e^{j\omega t}\},
+\]
+and in polar complex form as
+\[
+i(t)=\Re\{I_{0}\phase{\theta}e^{j\omega t}\}.
+\]
+Finally, we can simplify the notation by dropping the implied
+$e^{j\omega t}$ term and the $\Re\{~\}$ operator, leaving the phasor
+notation:
+\[
+\mathbf{I}=I_{0}\phase{\theta}=I_{0}e^{j\theta}=
+I_{0}(\cos\theta+j\sin\theta),
+\]
+where the boldface $\mathbf{I}$ reminds us that the phasor quantity
+$\mathbf{I}$ is a complex number.  The important advantage of this
+approach is that the mathematics involves mostly simple algebraic
+operations on the magnitudes and phases.
+
+It is interesting to look at the complex ratio of phasor voltage and
+phasor current, $\mathbf{V}\!/\mathbf{I}$, which is called the
+\emph{impedance}~$\mathbf{Z}$.  For the basic circuit elements we
+find:
+\begin{itemize}
+\item Resistor, $R$: $\mathbf{Z}=R$,
+\item Inductor, $L$: $\mathbf{Z}=j\omega L=
+  \omega L\phase{90^{\circ}}$,
+\item Capacitor, $C$: $\displaystyle\mathbf{Z}=\frac{1}{j\omega C}=
+  -j\frac{1}{\omega C}=\frac{1}{\omega C}\phase{-90^{\circ}}$.
+\end{itemize}
