[Tex/LaTex] Ohm symbol in latex

symbols

I have gone through symbol charts of latex and could not find how to put an ohm symbol. Like \theta, \omega, is there some command for ohms symbol?

Best Answer

You can use \usepackage{siunitx}. After that just input as \si{\ohm}. If you want to use a specific value it is better to mark it up like \SI{1}{\ohm}.

You simply type \LaTeX. One problem with this is that if you type it a lot of times in your text you will need to type \LaTeX\␣¹ (i.e., followed by \ and an actual space) to force a space after it.

Also personally I find the capitalization of L and T leads to typing errors, so I redefine the command as follows:

\newcommand{\latex}{\LaTeX\xspace}
\newcommand{\tex}{\TeX\xspace}

\xspace is from the xspace package. Additionaly, writing \LaTeX{} adds the space after.

^{¹ ␣ is used here to represent a normal space "", which wouldn’t show up at the end of Markdown code markup.}

Here is a custom-designed Bezier-curve flame in TikZ combined with a dotless letter ‘i’:

candle examples

Here is the source:

\documentclass{minimal}
\usepackage{tikz}

\newcommand{\iflame}[2]{%
  \begin{tikzpicture}[scale=#1]
    \fill[color=#2]
      (0,0) .. controls (-1.5,1.25) and (.5,2) .. (-.2,4)
            .. controls (1,2.5) and (1,.5) .. (0,0);
  \end{tikzpicture}
}

\newcommand{\icandle}[1]{%
  \rlap{\kern-.0275em\raisebox{1.2ex}{\iflame{.035}{#1}}}$\i$%
}

\begin{document}

\noindent
el\icandle{red}te\\
el\icandle{orange}te\\
el\icandle{yellow!80!red}te\\
el\icandle{gray}te\\
elite\\
\par

\end{document}

If you find the serifs on the ‘i’ to be undesirable, you can substitute instead a vertical rule of height 1ex, depth 0ex, and width .7pt, with about .09em kerning on each side, and then lower the flame by .1ex. I tried it both ways and I personally like it better with the serifs on the ‘i’.

Addendum

I just noticed today that the middle three letters of “elite” are “lit” and that the last four letters are “lite”. There is also the visual pun “e-lite”, e.g., “electronic light.”
