The SI unit for electrical conductance is a siemens (S). It is inversely related to electrical resistance. Electrical conductance is denoted with the letter G. Due to their incredible conductivity recent research focuses on graphene and materials that have a similar 2-D structure.Įrnst Werner von Siemens Definition and Units of Electrical ConductanceĮlectrical conductance is the ability of a material to conduct electricity. New superconductive materials are being developed.
If we could do that, we would be able to make high-speed trains that travel much faster than the trains we currently have.Īs you can see, the interest of researchers and engineers across the globe in superconductivity is obvious. In addition, using superconductive electromagnets would help us solve the problem of thermonuclear energy synthesis. If we use superconductors, we can reduce the size while simultaneously increasing the power of all electrical devices and mechanisms such as generators, transformers, and motors. An indirect benefit of studying superconductors would be the reduction of our carbon footprint and pollution caused by burning fossil fuels, and the impact on the environment in general.īesides, using superconductors in the industry and transportation would revolutionize technology, with benefits for the entire human population. Success in this venture would eliminate the necessity to “pay” for using this most convenient type of energy because it would prevent large energy losses during energy generation, conversion, and transportation that we have to deal with today. We could say that creating superconductive materials, along with developing thermonuclear energy is the dream and the philosopher’s stone of the 21st century. While the term “electrical conductance” is familiar mostly to electrical engineers and physicists, almost everyone heard the word “superconductor”, due to the popularity of superconductors and their frequent coverage in mass media.
