Which symbol denotes the unit of electrical resistance?

Explanation:
The symbol for the unit of electrical resistance is the Greek letter omega, Ω. Resistance is measured in ohms, and you’ll see values like 100 Ω on schematics to indicate 100 ohms of resistance. This ties to Ohm’s law, where R = V / I, linking resistance to voltage and current. The other terms point to related quantities: ampere is current (A), volt is voltage (V). The word “ohm” is the unit name, but the symbol used in notation is Ω.
