Term
|
Definition
| Millikan used negatively charged oil droplets and let them go through a tiny hole in a metal plate. Millikan then charged the plate in the above the drop, causing it to become attracted towards it. By repeatedly doing this, he could make the oil drop "dance" and be suspended in midair. As a result he was able to calculate the charge on an electron. |
