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
“IS LIGHTNING A FORM OF STATIC ELECTRICITY?”
Kite Flying Experiment
• Invented the lightning rod.
• Charge is conserved.
What do you call the jar that serve as a storage for the collected charge?
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?
Alessandro VoltaBasic Info:Born: 18 February 1745Died: 5 March 1827Gender: MaleOccupation: Physicist and ChemistNationality: Italian
Voltaic PileConsists of silver and zinc disc separated by cardboard.
Named after him the unit of measurement for electric potential,
Volts.
André-Marie AmpèreBasic Info:Born: 20 January 1775Died: 10 June 1836Gender: MaleOccupation: Physicist Nationality: French
Measures the flow of charge per second or
current.
