I've drawn a simple circuit diagram with CircuiTikZ, but my wires do somehow reach into my resistors which doesn't look very pretty. I guess this is quite easy to fix, but I couldn't do it.
\documentclass{article}
\usepackage[european,straightvoltages]{circuitikz}
\begin{document}
\begin{circuitikz}
\draw (0,2) to[open,v=$u_q(t)$] (0,0);
\draw (0,2) to[short,o-] (1,2);
\draw (1,2) to[R, l=$R$, v>=$u_R(t)$] (2,2);
\draw (2,2) -- (3,2);
\draw (3,2) to[L, l=$L$,v>=$u_{ind}(t)$] (4,2);
\draw (4,2) -- (5,2);
\draw (5,2) to[short,i=$i(t)$] (5,0);
\draw (0,0) to[short,o-] (5,0);
\end{circuitikz}
\end{document}
(1,2)
and(2,2)
is(1,0)
, and with default TikZ settings that is 1cm. By default, the resistor is bigger... You can scale every component see the manual for example with\ctikzset{bipoles/length=.8cm}
