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.

What does Alessandro Volta invented?

Voltaic pile is now known as?

What is the unit for current?
