Which scientist first experimentally demonstrated the quantisation of electric charge through his oil-drop experiment?
ACoulomb (1785)
BFaraday (1830s)
CMillikan (1912)
DFranklin (1750)
Answer & Solution
Correct answer: C. Millikan (1912)
Quantisation was suggested by Faraday's laws of electrolysis but experimentally demonstrated by Millikan's 1912 oil-drop experiment. Coulomb formulated the force law; Franklin established the sign convention.
