Very good video, shame he got mixed up on the charge of the oil drop. The x-rays that radiate through the walls of the vessel ionise the oil drop, hence giving it a negative charge. This also means that the + and - plates need to be swapped, otherwise the electric force would be in the same direction as the gravitational force (+ plate attracts negatively charges atoms)

Your ability to pace the explanations step by step is something i strive to do myself, and your kinesthetic sense to work with your paper stuff is absolutely phenomenal. I was genuinely in awe at every little diagram and how you were able to fluidly make each dynamic object move in the way that you had. This is one of my favorite videos i have ever seen.

Thanks to you, chemistry is still is my favourite subject. My teacher's ridiculous explanations had made me almost hate chemistry. I owe you a lot. Thanks a million times.

It works in the same way. The reason they become negative is because the X-rays ionise the air molecules and the delocalised electrons then attach onto the oil droplets causing a negative charge. In this case, the electrodes would just be reversed and the oil suspended again.

The reason of aquiring negative charge is that the x rays here is used as a kicking tool, these rays kick out the electrons from the gases present inside and gases get ionized and after that the free electrons ionize the coming oil droplets with negative charge since in this case the oil droplets get electrons and thus it becomes negatively charged and at last Milliakan and fetcher was able to calculate the exact value of that negative charge.

You are right, the velocity will not be zero unless it is pulling by another force greater than the force of gravity.I am confused too.I think they should measure the velocity of the oil drop in order to know when it is constant.

Its quite mixed up . The exact thing should be that the upper plate is to be + and the bottom plate is the - more over, the oil droplets doesn't contain the positive charge but a negative charge . The oil droplet got this charge from the beam passed through by the x rays

Both ways are right First case when the x rays provide the oil drops with enough energy so they lose electrons and get a positive charge (in that case el3ctrode is up) Second case is when the x rays provide other molecules with enough energy so they lose electrons which the oil drops gonna take and get a negative charge (in such case the cathode is down)..^^

Sir, how and why does the oil drop lose its electron while passing through the metal plates??

@mundoscience6922

3 жыл бұрын

That's a point I wanted to comment. They don't lose electrons, the air is irradiated with x-ray and this irradiation rips off electrons from the molecules of air. The oil drops, as they come down through the plate, they "grab" those electrons that were taken off the atoms of the air molecules and this is when the oil drops become negative. And in this case, the plates have to be the opposite to the ones in the video, because then the one with positive charge will be above so it can atract the negative drops of oil.

You forgot the X-ray to ionize the droplets.

Provide enough energy to an oil drop and you will ionise the drop. You will provide enough energy that an electron leaves the oil drop behind. In this case, this energy is being provided by x-rays.

how they measure the droplets mass?

@lordchipmonk1

6 жыл бұрын

Before turning on the electric field, the droplet is allowed to fall and reach terminal velocity. At this point, the force from gravity is balanced by the force from air resistance (the drag force). The terminal velocity allows one to determine the radius of the oil drop, (both the force from gravity and the drag force are dependent on the radius). With that obtained, the drop can be (hopefully) assumed spherical and the density of the oil is known and voila, one can calculate the mass.

Great effort put into making this video and nice explanation of the experiment..........Love your video

I think you have made a mistake. There are x rays in the real experiment. X rays hit the electrons in the air and electrons split from their nucleus. Oil drops that are sprayed on the air takes the electrons and become negatively charged. The top plate is positively charged so it pulls the oil drops. Other than that your explanation is perfect. When you think about it you can realize that there is no effect on the oil drops to make them positively charged so there is a mistake. If it is complicated for you, this link explains better than me: global.britannica.com/science/Millikan-oil-drop-experiment English is not my first language sorry for any fault.

2:40 for anyone wondering how the oil drops got charged, it was such that x rays were passed through the system, which ionised the gas particles inside it. Due to collison with the gaseous ions, the oil drops gained a charge. Hope it helps

I normally think of this experiment as imparting a negative charge to the oil drops. and the charged plates being reversed from how they are represented here. Can you discuss this please.

I think you got the charges of the plates reversed. Also, you didnt say anything about the xray that he used to add charge to the oil droplets. Research again please. And redo this video.
