2019 will be a year of international change. We have already explained here at Cbadtech why the measurement of the kilogram will be modified, but not only the basis of measurement of the mbad by the international system (SI) will be modified. Ampere, a fundamental unit of electrical current measurement, will also be modified next year.
But do not worry, this change will not require you to change the house wiring or affect the operation of electronic devices. . The measure is not intended to change the way electricity is measured, but to perfect what is the amp unit itself
According to the researchers, the main problem is that the electricity supply is being used. Ampere is that it can not be scientifically proven. Since its creation in 1948, the ampere has been defined as the constant current in which, if it were held in two parallel conductors, rectilinear and infinitely long, of negligible circular section and located in a vacuum at a distance of one meter. Another, would produce between these drivers a strength of 0.0000002N – the base value of an ampere unit.
That is why scientists change the ampere is measured and, as of May 20, 2019, the unit will be based on the elementary electric charge, ie the new base of the unit of electrical current will count the individual flow of electrons. Although the physical experience of measurement of the elementary charge can only be performed in quantum laboratories of last generation, it is already a big step forward compared to the current measurement, impossible to prove experimentally.
But, as we have already mentioned, the change will not change anything for the average consumer. The electrical installations will continue to operate unchanged, as will the electronic equipment, and even the monthly amount of electricity from your local electricity supplier will not be read.
The most important change will occur in the industry and research laboratories. . Precision equipment, such as MRI devices, will need to be recalibrated and should greatly help the smartphone industry. Indeed, by modifying the measurement, it will be possible to calculate more precisely the number of life cycles of the battery, which will facilitate research to create smaller and more durable batteries.
