Hint: The SI unit of measurement is the standard international unit of measurement. The Si unit of the measurement is acceptable at all parts of the world. Use of SI units reduces the communication gap in different parts of the world.
Complete step by step answer:
There are several types of the unit in the measurement system. Basically, the physical quantities are divided into three categories:
(i). Fundamental unit: The fundamental units are the base units. These units are the independent units in the system of measurements. There are seven fundamental quantities which are: length, mass, time, temperature, current, amount of substance and luminosity.
(ii). Derived unit: The derived units are the units expressed in the fundamental quantities.
(iii). Supplementary unit: The supplementary units are the unit that is dimensionless. There are only two supplementary units: Radian and steradian
Current is the fundamental quantities. The SI unit of the current is ampere. The unit of the current is named after Andre-Marie Ampere. He was a French physicist and Mathematician. He made his great contribution to classical electrodynamics. His inventions include the solenoid and electric telegrams.
Ampere is defined as the flow of charge in the conductor in the unit time. One ampere is the current flows in the conductor when one coulomb charge flows for one second.
Note:
The CGS unit of the current is biot. It is also called abampere. This unit is named after French physicist Jean Baptiste Biot. He also contributed to Biot-savart's law. The relation between the SI and CGS unit of current is:
1 ampere = 10 abampere
