This is such a good explanation for anyone, especially for people like me where physics isn't my major and very far outside my comfort zone. Thank you!
I very much agree, I'm just starting my studies in physics and this video explained the concept i a very easy to understand way, even for those who are beginners.
You're a legend. I spent 2 hours trying to find an explanation for this and you've explained this better than anything I've seen anywhere else! Thank you!
Amazing video! You make it very easy to understand compared to literally every other video I've watched on this topic. Keep going with the amazing lessons!
the song at the beginning is everything:)++ thanks a lot for explaining the difference between the induction and conduction in an electroscope I was a bit confused about this part:>
Excellent! Everything is clearly explained in terms that are easy to understand. I was able to watch this once and walk away with a better understanding. Then anything I have read so far. Thanks
When contacting/ conducting the metal and glass rod, I believe the electrons would jump over from the metal to glass rod until the voltages relative to one another are equal.. That is not all the electrons would jump over.. This is a great video
Thank you for the excellent videos! You note that (3:30) extra electrons on a a charged insulator can't move but at 6:20 note that when the charged insulator touches the conductor, the electrons do move onto the insulator; how are they moving in this case as it's an insulator? I figured there would be no induction or conduction on the insulator since there's no friction?
I think that since the plastic stick will be negatively charged at one area, when you put it in contact with the electroscope, this will cause depolorisation in the electroscope ( + up, - down). Because the electroscope is now + above, it will want electrons so it will take them from the plastic stick until the stick becomes neutral. I think insulators dont have a high affinity for electrons like metals do thats why :).
At 3:30 he was trying to tell difference between neutral and charged.Then he explained at 6:20 that how charges move in insulator.As he has best teaching style
Hey ... Here when you are talking at 3.30 you got it right that charges are not mobile in insulator.. And at 6.20 the electrons from the conductor(the ball on the electroscope) move to the rod (insulator) not from insulator to conductor.. So still the concept that electrons in insulator are immobile is standing !!
Thanks so much for this excellent and lucid explanation of electrostatic induction and conduction. Please explain when rubbing two different materials what determines the direction of electron flow ?
Quick question: on 7:10 , electrons flew through the "plastic rod" to the plates. I understand that if you contact a metal rod for example, to the metal ball on the elctroacope, you're gonna provide a path from which electrons can easily get pushed or pulled depending on what charge the rod has. What I don't understand is the same thing happening while you contact a non-metal rod, lets say plastic which is on 7:10 . Why does the same thing happen? How can electrons flow from their fixed position while plastic is not conductive not letting the electrons flow easily? I'm confused.
Since work is being done on the metal leaves when the rod is brought close, how does the energy of the rod change? Is this provided by the mechanical act of bringing the rod close, or is there an internal change in the rod?
If the rod is an insulator, electrons cannot flow easily from the rod to the electroscope or vice versa. The effect is minimal. You need a charged conducting rod with an insulating handle. Also, at 6:17, it is also not true if a charged rod touches a neutral electroscope, the electrons flowing from the electroscope will neutralise the charged rod. When a charged conductor touches another neutral conductor, the electrons flow between the 2 conductors until they have equal potential and thus charges stop flowing. Hence, the charged conductor will have less charge now and the electroscope is charged with the same polarity as the charged conductor.
Can someone please explain what happened to the protons in the electroscope for the conduction example at 7:25? I understand that the electrons are transferred to the electroscope but what happens to those protons since protons can't move
There was more electrons than before, therefore the rod became negative. The protons was still there, it's just that he wanted to show that the overall system became negative
love the video. helpful for my study. If lets say protons cannot move, then why positive charges can move about? If we rub the insulator rod with a plastic, can we control we want it to be positive or negative charged?
You said all electrons are attracted to the charged glass rod so they are moving upward, but what about the electrostatic effect that occur between those electrons?
what will happen if you bring a negatively charged strip near the electrode and ground the electroscope. will there be an electron transfer? assuming you have already grounded it before bringing the strip close.
Okay......I have a question. Firstly I took the negative charges in the glass from the electroscope....... Now if I rub the glass again and make it negatively charged, what will be the scenario if I want to do an induction with the electroscope?
how about charging permanently through induction like when you bring the rod near the sphere and then touching your finger on the sphere now it will have the opposite charge.
Wonderful explanation. How does one coulomb of charge (1 amp) be able to carry either 9 volts DC or 120 AC or 240 volts AC. Are EXTRA electrons added to each coulomb OR are they JUST PUSHED harder based on the voltage. Are Volts an imbalance of electrons? confusion.
I would have liked it better if you had left some charges on the rods and electroscope. There are no items with just one kind of charge on them. Better to put some positive and negative charges on the electroscope and leave the positive ones alone. Then add or take off the negative charges. This is a great explanation, but it leaves a false idea about the total number of different charges on the electroscope and the charging rod. Thank you for you contributions.
I didn't hear what type of materials you use to perform this experiment. My son and I used a PVC pipe and cotton cloth to make a negative charge. Then a polyester sheet and a glass rod to make a positive charge.
Doubt. The electrons is the only moving charges Using glass rod , Glass is an insulator then the electrons are fixed it can't move then how the electrons moved to cloth while rubbing and made the rod possitive... While using plastic, It is also an insulator how does it become negatively charged. While rubbing, electron can move from cloth to surface of plastic but the plastic is a neutral thing how does is attracted electrons while it is not a positivly charger plastic rod..
What I’ve learnt is that glass has a greater comparative tendency to lose electrons to become positively charged while plastic (pvc) has a greater comparative to gain electrons to become negatively charged.
This is such a good explanation for anyone, especially for people like me where physics isn't my major and very far outside my comfort zone. Thank you!

best explanation ever
This was actually really helpful, a very pedagogical explanation. The pictures and animations were very helpful to understand the concept.
Mr. Anderson's been saving my grades for 7 years now
Amazing video! You make it very easy to understand compared to literally every other video I've watched on this topic. Keep going with the amazing lessons!
BOZEMAN SCIENCE ROCKS!!!!!!!!!! Lots of love Mr. Andersen
You are the master of Physics. Thank you very much :)
Your videos are so clear and your teaching style is so effective thank you so much!
First teacher explains in human language. Not everybody is charged to teach in understandable way
You're one of the best teachers i've ever seen!
This is so easy to understand, i was so confused before watching this video but now i understand it fully. Thank you!
the song at the beginning is everything:)++ thanks a lot for explaining the difference between the induction and conduction in an electroscope I was a bit confused about this part:>
Conduction happens because of friction and induction occurs because of contact
U r teaching awesome. U really deserve an award for ur teaching.
Excellent! Everything is clearly explained in terms that are easy to understand. I was able to watch this once and walk away with a better understanding. Then anything I have read so far. Thanks
THANK YOU!!!!! You don't know how much you help people and make learning easier for us, seriously! :)))
Mr. Anderson you are the best and I'm a fan !
This was very helpful. I have my physics exam on next week and this has really helped!!

Thank you so much. I'm in grade 9 AP and I was having so much trouble understanding this but now i do. This was very helpful.
Thank u sooo much esp when u summarised at the end it made it more easier to understand am subscribing now! Thank again❤
Great teacher , you interpret us in easy language
Thanks a lot! I got full marks on the test about this because I came across to your channel! Thanks again and it really helped me.
thank you so much this helped me on my science test your a god send man
Thanks so much for this excellent and lucid explanation of electrostatic induction and conduction. Please explain when rubbing two different materials what determines the direction of electron flow ?
Your explanation was very clear. thank you.
I found it extremly useful for my CLIL (content and language integrated learning) Physics class
It sounds like you are high school teacher
why are the electrons not fixed in the charged plastic rod?

This was a good video you taught classification and variation very well keep it up
every good! glad I watched this before my exam tomorrow!!!
What if you are solving any hard que during exam?
@@ketansingh1652 hahaha sorry this exam was years ago so I don’t remember what was on it
Thank you very much for sharing. I love all your videos
Thank you! better than all of the other videos
This was the video I was looking for.
Thankx for the help
Electroscope explanation was awesom
Amazing explanation, this have really build onto my knowledge of the photoelectric effect experiment with the electroscope. Thanks again.
What a good and useful video it is!
Since work is being done on the metal leaves when the rod is brought close, how does the energy of the rod change? Is this provided by the mechanical act of bringing the rod close, or is there an internal change in the rod?
This is as same as what Mr. Ahmad taught us in the science class, it is the thing that I am going to be tested on Tuesday.
thankyou soo much helped me a lot !! i have been struggling with this topic

love the video. helpful for my study.
If lets say protons cannot move, then why positive charges can move about?
If we rub the insulator rod with a plastic, can we control we want it to be positive or negative charged?
More than helpful , thank you very much sir.
Very good explanation
Great class more than a online teacher here taught us
Many Thanks for this video. It is really helpful

Thanks for this video! Learned everything I needed to. Clear, thorough and relevant information. :D
awesome. excellent explanation. i couldn't get in in my class . thanks again
Is it possible to determine the type of charge of an object using a gold leaf electroscope?
what will happen if you bring a negatively charged strip near the electrode and ground the electroscope. will there be an electron transfer? assuming you have already grounded it before bringing the strip close.
Huge thank you from Belgium !
9years had passed and still helps highschool childrens

Really well explained. Thanks for this!
Love this teaching ❤
Thanks for your video, but what i wanted to know is why not electron move in insulator material and do in conduct material?
Genius! Thanks a lot man!
very good explanation and animation
Superb explanation Sir !
where did the protons go inn the last example, i thought protons couldn't move between two objects? please can someone explain
But what happens when the electro scope is positivity charget and it induces a also positive charged material
Thanks Buddy. You are very informative. Your videos are very helpful .
Wonderful explanation. How does one coulomb of charge (1 amp) be able to carry either 9 volts DC or 120 AC or 240 volts AC. Are EXTRA electrons added
to each coulomb OR are they JUST PUSHED harder based on the voltage.
Are Volts an imbalance of electrons? confusion.
thankyou! I finally understand how the electroscope works!
simple basic and helpful thank you Mr.Andreson🤗
Wow great explanation, rock on
He has a website called bozemanscience.com if y’all need more videos
So positive charges do not migrate? Thank you
Thnks... With regards from India

Those animated pictures.... Do I undestand the movement of electrons on the outside of a dielectric, not inside it, right?
I didn't hear what type of materials you use to perform this experiment. My son and I used a PVC pipe and cotton cloth to make a negative charge. Then a polyester sheet and a glass rod to make a positive charge.
Thanks a lot!!! Your explanation is the best!!!

Yah this is helpful and your skill is awesome via your every wors....
Awesome STUFF BUT WHEN WILL THE LEAF ATTARCT TO EACH OTHER OR IN ITHER WORDS, COLLAPSE?
whats the difference between the glass rod and plastic?
This helped me a lot, thank you!
it was really helpful ......Good job :)
thanks bozeman ur a god
When we use plastic , how electrons are added?? Plz answer
But how do you know when objects become positively or negatively charged after rubbing them ?
