What is the name of the SI unit of capacitance, and after which scientist is it named?
AThe volt, named after Alessandro Volta
BThe coulomb, named after Charles Augustin de Coulomb
CThe farad, named after Michael Millikan
DThe farad, named after Michael Faraday
Answer & Solution
Correct answer: D. The farad, named after Michael Faraday
1. The unit of capacitance, coulombs per volt, is given a special name.
2. That name is the farad, abbreviated F.
3. It is named after the English physicist Michael Faraday.
4. The volt is named after Volta and the coulomb after Coulomb, so those name-unit pairings belong to different quantities entirely.
