\end{document}Common Use Cases
The Omega (Capital) symbol is commonly used in the following contexts:
Electrical Resistance
Symbol for ohms (electrical resistance).
Code
Resistance: $R = 100\Omega$Output
Resistance: R = 100Ω
Sample Space
Used for the sample space in probability.
Code
Sample space: $\Omega = \{H, T\}$Output
Sample space: Ω = {H, T}
Complete Examples
Ohm's Law
Ohm's law with ohm unit
\documentclass{article}
\begin{document}
Ohm's Law: $V = IR$, where $R$ is in ohms ($\Omega$).
\end{document}Probability Sample Space
Sample space in probability
\documentclass{article}
\begin{document}
For a coin flip, the sample space is $\Omega = \{\text{Heads}, \text{Tails}\}$.

Which method should I use?
We recommend using the method marked as "Recommended" above. However, the best method depends on your specific needs:
- \Omega: Uppercase Omega - ohm or sample space
Where do I use this symbol?
This symbol can be used:
- In mathematical equations (math mode)
- In regular text (if using text mode)
- In various document environments
Can I use this in display mode?
Yes, symbols that work in math mode (between $ $) also work in display mode (between $$ $$). This allows you to display the symbol on its own line with larger formatting.
