The symbol "ω" (Ohm) represents the unit of electrical resistance in the International System of Units (SI). It is named after the German physicist Georg Simon Ohm, who formulated Ohm's Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant. One Ohm is defined as the resistance that allows one ampere of current to flow when one volt of electrical potential is applied. In practical terms, understanding Ohms is essential for designing and analyzing electrical circuits, ensuring they function safely and efficiently.
