Scientists in Electricity

Charles CoulombBasic Info:Born: 14-Jun-1736Birthplace: Angoulême, FranceDied: 23-Aug-1806Location of death: Paris, FranceGender: MaleRace or Ethnicity: WhiteOccupation: PhysicistNationality: French

Coulomb's law says the electrical force between two charges (q1) and (q2) is proportional to the

product of the two charges divided by the distance between

the two charges squared

SI unit of charge is named after him.1 coulomb= 6.24 x

10^18 electrons

What is the SI unit of charge?

What is the relationship of electromotive force and the charge of the two charged bodies??

Benjamin FranklinBasic Info:Born:  January 17, 1706Died:  April 17, 1790 Gender: MaleRace or Ethnicity: WhiteOccupation: PhysicistNationality: American

Georg Simon OhmBasic Info:Born:  March 16, 1789Died:  6 July 1854Gender: MaleOccupation: Physicist and mathematicianNationality: Bavarian (German)

Determined the relationship between

current, resistance and voltage.

V=IR

What is the equation for Ohm’s Law?

What does V represents in V=IR?
