What does the symbol "Omega" represent?

The symbol "Omega" represents resistance in electrical terms, which is denoted by the Greek letter Ω. This unit of measure indicates how much a material opposes the flow of electric current. In the context of Ohm's Law, resistance is a crucial concept as it relates voltage, current, and resistance in an electrical circuit, expressed by the formula V = IR, where V is voltage, I is current, and R is resistance. Understanding resistance helps in forecasting how much current will flow in a circuit when subjected to a certain voltage and allows engineers to design safe and efficient electrical systems. In contrast, current is represented by the letter "I," voltage by the letter "V," and power by "P," thereby solidifying Omega's exclusive representation of resistance.
