Who introduced the idea of electric lines of force?
Think it through first, then pick an option.
- a Michael Faraday
- b W. E. Weber
- c Alessandro Volta
- d A. D. Coulomb
Answer and explanation
Correct answer: a Michael Faraday
Michael Faraday first introduced the imaginary lines of force to show the electric field.
Why the other options are wrong
- b W. E. Weber: Weber's name is not linked with lines of force in this chapter; the book says Faraday drew them first.
- c Alessandro Volta: Volta's name is not linked with lines of force in this chapter; Faraday drew them first.
- d A. D. Coulomb: Coulomb gave the law for the force between two point charges (10.4), not the idea of lines of force.
