The symbol Ω represents:

  1. current.

  2. resistance.

  3. amperes.

  4. power.

The correct answer is: resistance.

The symbol Ω, known as "ohm," specifically represents resistance in the context of electrical circuits. Resistance is a measure of the opposition to the flow of electric current in a conductor. Understanding this concept is crucial in electrical engineering and physics, as it helps to define how much current will flow through a material when a certain voltage is applied, according to Ohm's law (V = IR), where V is voltage, I is current, and R is resistance. In contrast, current is measured in amperes (A), which represents the flow rate of electric charges. Power, measured in watts (W), refers to the rate at which energy is transferred or converted, while other units of measure might be involved in these calculations but do not specifically relate to the Ω symbol. Knowing these distinctions helps clarify why Ω is accurately associated only with resistance.
