The unit of resistance is the ohm, and it is denoted by the symbol "Ω" (the Greek letter omega). The ohm is named after Georg Simon Ohm, a German physicist who formulated Ohm's law, which describes the relationship between voltage, current, and resistance in an electrical circuit.

In practical terms, resistance measures the opposition that a material or component offers to the flow of electric current. The higher the resistance, the more difficult it is for current to pass through the material or component. Conversely, low resistance allows current to flow more easily.
