\section{{\tt L}: Inductor}
%------------------------------------------------------------------------
\subsection{Syntax}
\begin{verse}
{\tt L}{\it xxxxxxx n+ n-- value}\\
{\tt L}{\it xxxxxxx n+ n-- expression}\\
{\tt L}{\it xxxxxxx n+ n-- value} \{{\tt II=}{\it initial-current}\}\\
{\tt .INDuctor} {\it label n+ n-- expression}
\end{verse}
%------------------------------------------------------------------------
\subsection{Purpose}

Inductor, or general flux storage element.
%------------------------------------------------------------------------
\subsection{Probes}

The following probes are available in addition to those available for
all basic elements. 

\begin{description}

\item[{\tt DT}] Time step.  The internal time step used for this
device for numerical integration.  It is not necessarily the same as
the global time step.

\item[{\tt TIME}] Time.  The time of the most recent calculation of this
device.   It is not necessarily the same as the global time.

\item[{\tt TIMEOLD}] The time of the previous calculation of this
device.  It is not necessarily the same as the global time.

\end{description}
%------------------------------------------------------------------------
\subsection{Comments}

{\it N+} and {\it n--} are the positive and negative element nodes,
respectively.  {\it Value} is the inductance in Henries.

%%%Specifying a {\tt METHOD} overrides the default method from the
%%%{\tt options} command.  The valid methods are the same.

The (optional) initial condition is the initial (time = 0) value of the
inductor current (in Amperes).  
Note that the initial conditions (if any)
apply only if the {\tt UIC} option is specified on the {\tt transient}
command.
