TΩ(teraohm)

Teraohm (TΩ) is a unit of electrical resistance in the field of electronics and electrical engineering. It is a part of the International System of Units (SI) prefix system and represents one trillion ohms (1 TΩ = 10¹² Ω).

Electrical resistance is a measure of the opposition to the flow of electrical current through a material, such as a conductor or insulator. The ohm (Ω) is the standard unit for measuring electrical resistance, and the teraohm is used when dealing with extremely high resistance values, often found in insulating materials or large electrical systems. Having a resistance of 1 TΩ means that a potential difference of 1 volt will result in a current of one trillionth (10⁻¹²) of an ampere, illustrating a significant opposition to the flow of current.

Ω(ohm)

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.
