Omega symbol is also used for resistance unit in physics. Of course, there are different packages like Siunits. However, the whole work was completed with the help of the following simple method.

```
\documentclass{article}
\begin{document}
\[ 10\mu\Omega \]
\[ R_1=10\Omega \]
\[ 10\Omega-6\Omega=4\Omega \]
\end{document}
```
