HELLO HIVE
In a quest to determine the charge of a single electron American noble prize winning scientists Robert Millikan came with a discovery that opened so much more in the field of science as a whole he was a physicist who devoted a lot of his time trying to make discoveries that will shape the world of science and one of his discovery has to do with the charge that an electron carries. Electron had already been discovered way back in 1897 by another scientists but the discovery didn't give much light on many of the properties that the electron carries this property is the most important property that the electron has because this property helps us understand how electron works during chemical reactions and synthesis.
The electric field in the chamber is what makes this experiment possible because it counteracts the force of gravity allowing scientists get the precise measurement of the drops motion.
Students of physics in universities around the globe are taught how this scientist made this discovery and we get to pick up that knowledge at some point during our journey to shape our careers though the instrument he used then might have been slightly modified to make it easier now.
Apparatus: Millikan oil drop apparatus, an AC adapter, power supply, Nonvolatile oil, digital stopwatch, digital multimeter, atomizer, high voltage well-regulated, and banana plug patch cords. There is other equipment but this is the most basic one.
Procedure: we have to first disable the droplet viewing chamber use a micrometer to measure the thickness of the spacer plate and record it, reassemble it again by placing the plastic placer and the upper capacitor into the lower capacitor, connect high voltage DC supply to around 500VDC, record plate voltage and thermistor resistance, put nonvolatile oil into atomizer by using a spray droplet position you can now go ahead with what you are provided within the manual that will guide you on what to do.
Experiments like this don't require much hard work once the apparatus is working and the setup is okay, the most important part of this is watching the oil droplets in the viewing chamber for now I haven't completed the remaining parts of the experiment which is the calculation part of it but I will do that very soon so that I can submit my report to my supervisors in the lab.
