How can I draw a wattmeter using LaTeX and circuitikz? I want to use the one with a circle and a cross inside.

    Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. – Ruben Dec 20 '14 at 13:44

  • There's no mention of 'wattmeter'. – Attila Dec 20 '14 at 14:48

Since there is no wattmeter in the circuitikz, you need to draw one. Here the solution modifies the DC voltage source and create a wattmeter via newcommand that takes one argument for label

enter image description here



{  % #1 = name
\draw[thick] (#1) circle (12pt);
\draw[rotate=45,line width=1pt]   (#1) +(0,-12pt) -- +(0,12pt);
\draw[rotate=-45,line width=1pt]  (#1) +(0,-12pt) -- +(0,12pt);

\draw (-1,0) node[ground] {} to[V,l=$10V$] (-1,2) to[R=$4\Omega$] (2,2) to[R=$2\Omega$,] (4,2);
\draw (4,2) to[L, l=$\frac{1}{5}F$] (4,0);
\draw (2,2) to[V,color=white,name=M1] (2,0);
\draw (-1,0) to[short](4,0);

  • Great idea. How would I draw the name of the wattmeter? – Attila Dec 20 '14 at 15:14

    Use label as l=M1, right after the name=M1. If you need it on the left hand side, use l_=M1. Same as the skill in circuitikz. – Jesse Dec 20 '14 at 15:20
