Omega (symbol)

The Omega symbol (Ω) is used in various fields to represent different concepts, most commonly in physics and mathematics. In physics, it often denotes ohms, the unit of electrical resistance. In mathematics and engineering, Ω can symbolize the total amount of something, such as the end state or limit of a process, or the set of all possible outcomes in probability theory. The symbol originates from the Greek alphabet, where it is the last letter, signifying the "ultimate" or "final" in a sequence. Its use is context-dependent, reflecting either a measure, a boundary, or an extremal value.
