| Details | Ohm (Ω) is the unit of electrical resistance, represented by the Greek letter omega (Ω), in the International System of Units (SI). Electrical resistance measures how much an electrical conductor opposes the flow of electric current through it. The ohm is defined as the resistance between two points in a conductor when a constant potential difference of one volt, applied to these points, produces a current of one ampere through the conductor. In simpler terms, a conductor with a resistance of one ohm would allow a current flow of one ampere when the applied voltage is one volt. Higher resistance means that the material is less conductive and hence opposes the flow of electric current to a greater extent. The concept of resistance is crucial in the design and analysis of electrical circuits, especially in determining the proper flow of current through a circuit and understanding how different components (such as resistors) affect the performance and efficiency of the system. |
