@IRmShaDe I rubbed a normal drinking glass and a piece of vinyl cut out from window blinds that you roll up. Wash the glass thoroughly first with soap and hot water and rinse thoroughly to get any grease off. The rubbing takes advantage of the triboelectric effect. See my video "Triboelectric effect/series or triboelectricity" for which materials work and why. There's an annotation at the end of this video to click on for the triboelectric video and a link in the comments.
@RimstarOrg just watched the video. Again, thanks a million for posting all these videos, extremely useful and informative. it helped me understand alot more. thanks. =)
@AGuyWhoMakesVideos That's sort of a strange question. My guess is somewhere in your course material or lecture 3 specific things were listed, so my answer may be different. But here goes anyway: to detect a net charge on an object, to measure the relative magnitude of charge on different objects, and to determine the sign of the net charge on an object (using techniques like in this video.)
tnx for your response dear creation hehehe! we just tried it a while ago but plastics are not good as the one needed in the rubbing etc,,,, the charging hehehe we made use of celluloid!
@archiemedez18 In case it helps you find materials, I just added an annotation to the end of this video that will take you to my "Triboelectric effect" video that talks about the materials.
@DangJfjed I don't know what about the materials determines where they fit in the triboelectric series, which is a table that shows how positive or negative they become relative to each other. If you google "triboelectric series" and look at the list you'll see that there are other plastics that become more negative: polystyrene, acrylic, polyethylene, vinyl, silicon, to name a few.
@archiemedez18 You're very welcome. It is a tricky one to explain clearly but as long as you understand it you should do well. Feel free to ask here for help if you run into trouble.
@killerdude25 Electrons will move from the ground to the electroscope and the electroscope will become negatively charged. So when the ground and then the positively charged object are moved away, the negatively charged foils will repel each other. Physically it'll look the same as in the video but electrically everything will be the opposite.
@jndhillon Yes:) On a dry day, walk across a carpet with bare feet and you'll be positively charged (triboelectric effect.) That's why you get shocked sometimes when touching a metal object, electrons flow from the object to you. In this video I was more positive than the electroscope so the negatively charged object and the negatively charged leafs pushed negative charge onto me, plus my positiveness attracted some. But you might be negative relative to something that's more positive than you.
'any time you touch a charged object electrons will flow and the object will discharge'
But the gold leaf electrosocope is neutral in the start! So this is confusing me. Because in the vid, the object was neutral, and it was earthed.
Do you get what I mean?
And also it said ' if the object is + charged, electrons flow from ground through you and discharge the object. But the object is neutral! ugh.. I don't understand:(plz help?thanks
@Sindyrocks2009 I don't think I can help in the small space given for comments here. I sent you a friend request so I can send you a longer explanation in a message. If that's not okay then I can try in the comments but it will be a mess and may end up confusing you more.
Do you think that this concept would be too difficult for grade 6 kids to understand? I am planning some electricity lessons for a class of grade 6 kids.
@xxhintoftearsxx I think grade 6 kids could handle it. Demonstrate it a little at a time and give them hands on. Do some diagrams too. But at the same time, keep it simple. To see a kid explain an electroscope, go to youtube dot com slash NL126 and look at his video called Static Electricity.
@raLphIRE It averages around 8 views a day and seems to rank pretty high in relevant searches. There's probably just not that much interest. But I added "gold" and "leaf" just as you suggested. Thanks for the interest.
@xgusROX Good question. I don't see why it would. Those things may be putting out some electromagnetic waves, though they should be shielded to prevent some or all of that. Electromagnetic waves are given off by moving electrons. A charged object consists of en excess or a deficit of electrons, where the number of electrons doesn't change; their just sitting there.
@xgusROX A CRT tube type of monitor or TV does cause it to react, even if turned off for a while. The screen is a large capacitor and is charged when turned on and takes a while to loose its charge when turned off. I just tried it with my old TV and it reacted, but I just tried it with my LCD monitor and got nothing. I don't know about all the different types of monitors that exist these days though. Does anyone know if a plasma TV or monitor carries a static charge?
THANK YOU this helped me so much for my ap physics class!! your awsome!! this was such a good way to demonstrate it!!
