MCQ
Faraday law of electrolysis indirectly shows
- ✓quantisation of charge
- Bquantisation of angular momentum
- Cquantisation of current
- Dquantisation of viscosity
✓
Answer
Correct option: A.
quantisation of charge
a
Faraday's law says that amount of substance liberated or deposited at an electrode is proportional to quantity of charge passed through it. Thus, mass $ \propto $ charge. Since mass is quantised hence indirectly charge is quantised
