What evidence supports the quantisation of charge as demonstrated in Millikan's experiment?.
- A.The charge values measured were continuous
- B.The charge values measured were discrete multiples of a fundamental charge
- C.The charge values measured were negative
- D.The charge values measured were always zero
Model answer
What a good answer should say
- The charge values measured were discrete multiples of a fundamental charge
Explanation
Why this works
Millikan's experiment showed that the measured charge values were discrete and always multiples of approximately 1.6 x 10^-19 C, which is the charge of a single electron. This supports the concept of quantisation of charge.
