BECQUERELS
Becquerel’s is the S.I unit of radioactivity. Becquerel’s (Bq) is used to measure the activity of a radioactive sample is the average number of nucleus breaking up per second. For example – iodine 128 decays by shooting out beta particles. If in a sample, 40 nuclei break up every second then 40 40 beta particles are shot out every second, then the activity is 40 Bq.
Antoine Henri Becquerel was born in Paris on December 15, 1852, a member of a distinguished family of scholars and scientist .The bacqeral is named after him who received a noble prize along with marie curie and pierri currie.

CELCIUS
Celcius or also knon as the centigrade was found by the Swedish astronomer Anders Celcius (1701–1744). The unit was known until 1948 as "centigrade" from the Latin centum translated as "steps".
From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere with mercury as the base for the thermometer.later thou the standard international units body defiend kelvin(k) as the s.i unit of temeperature and not Celsius.

kelvin
The kelvin is a unit of measurement for temperature. It is one of the seven base units in theInternational System of Units (SI) and is assigned the unit symbol K. The kelvin scale is an absolute,thermodynamic temperature scale using o degrees as the point were all particles stop vibrating or moving. .
Lord kelvin was a Scottish mathematician and physicist who contributed to many branches of physics. He also calculated the age of the earth. He was born in Belfast in 1824. At the University of Glasgow he did important work in the mathematical analysis of electricity and formulation of the...

...and was most noted on his work on AC current and wireless communication. He also invented the tesla coil.The S.I unit of magnetic flux is named after him.
The tesla is the SI derived unit of magnetic field strength or magnetic flux density, commonly denoted as B. One tesla is equal to one weber per square metre,

VOLT
The volt is the derived unit for electric potential, electric potential difference, and electromotive force. One volt is defined as the difference in electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points.
Alessandro Volta (February 18, 1745 – March 5, 1827) was an Italian physicist who was known for inventing the battery. Volta is also known for making discoveries on electrostatics and meteorology. voltas battery design.
