What does the quantisation of charge refer to in the context of Millikan's experiment?.
- A.Charge can take any value.
- B.Charge is always negative.
- C.Charge exists in discrete amounts, specifically multiples of the electron charge.
- D.Charge is dependent on the mass of the particle.
Model answer
What a good answer should say
- Charge exists in discrete amounts, specifically multiples of the electron charge.
Explanation
Why this works
Millikan's experiment provided evidence that charge is quantised, as the measured charges were always integer multiples of the elementary charge of the electron.
