How current is measured?
Current is measured in Amperes (usually just referred to as “Amps”). An ampere is defined as 6.241*10^18 electrons (1 Coulomb) per second passing through a point in a circuit. Amps are represented in equations by the letter “I”. This is analogous to an increase in voltage that causes an increase in current.
What is unit of electric charge?
The unit of electric charge in the metre–kilogram–second and SI systems is the coulomb and is defined as the amount of electric charge that flows through a cross section of a conductor in an electric circuit during each second when the current has a value of one ampere.
What is the SI unit of electric charge and current?
coulomb
Where did JJ Thomson do his work?
In 1876 he obtained a scholarship at Trinity College, Cambridge, where he remained for the rest of his life. After taking his B.A. degree in mathematics in 1880, the opportunity of doing experimental research drew him to the Cavendish Laboratory. He began also to develop the theory of electromagnetism.
What scientists did JJ Thomson work with?
In addition to Thomson himself, six of his research assistants (Charles Glover Barkla, Niels Bohr, Max Born, William Henry Bragg, Owen Willans Richardson and Charles Thomson Rees Wilson) won Nobel Prizes in physics, and two (Francis William Aston and Ernest Rutherford) won Nobel prizes in chemistry.
What name is given his model?
The Rutherford model is a model of the atom named after Ernest Rutherford. Rutherford directed the famous Geiger-Marsden experiment in 1909, which suggested, according to Rutherford’s 1911 analysis, that J. J.
Where did JJ Thomson discovered the electron?
J.J. Thomson attended Trinity College at Cambridge, where he would come to head the Cavendish Laboratory. His research in cathode rays led to the discovery of the electron, and he pursued further innovations in atomic structure exploration.
