Name femtoohm
Category Electrical Resistance
Details A femtoohm (fΩ) is a unit of electrical resistance in the International System of Units (SI), representing 10^-15 ohms (Ω). It is a very small unit of resistance, which is used to measure extremely low resistance values, often encountered in the field of electrical engineering or physics, particularly when dealing with superconductors, high-performance materials or devices, and advanced sensing techniques.

In electrical resistance, one ohm (Ω) is the basic unit, defined as the resistance between two points in a conductor through which, when a constant voltage of one volt (V) is applied, one ampere (A) of current flows. Since a femtoohm is 10^-15 times smaller than one ohm, it represents extremely low resistance in electrical conductors or circuits.
