We miss you mam
@@rmarmy9449 i love u mam
Lekin cars me scratch ate hai
That person would be legend who is seeing this one day before the exam like me 😂😂
bruh believe me or not,its currently 1:37am right now and i have my science exam today at like 8am and now is when im watching this video lol
Nope😂🤣😂
Yeah 😅
Yeah
I am seeing this 4 hours before exam
but when the high current is flowing throughout the fuse wire melts so then the fuse will it work again after melting wire or we will have to replace it
At old times, when fuse wire user to melts we had to replace it but nowadays those fuses are used which can be just turned off when high current passes or can be turned on back again.
Hope it helps.
Thank you so much it's my first time studying from vedantu and i m really impressed thank you so much ma'am
Hello Ma'am
I have made Magnetic levitation Train{MANGLEV TRAIN }
As we have made it in our science kit
My name is Abhinav Singh of class7 of mayur public school
bruh believe me or not,its currently 1:37am right now and i have my science exam today at like 8am and now is when im watching this video lmaoo
Boy that’s messed up lol I am watching it a day before my exam 🤪
I'm watching at 9pm and I have my exam in the morning at 9 am. 😂😂😂
It was very difficult to study this chapter and I don't have interest in this chapter
After mam teaching it is very easy and interesting
It's nothing about who teaches it's about we understand and keep interest ma'am also teach do well
It depends on us and the person who teach us
Hey, am getting confused in electrolysis and electroplating..plz clear my confusion
great
Electrolysis refers to the decomposition of the substance by an electric current and electroplating is the process of coating a layer of metal to another metal .
Hope it helps you
@@aayushi8715 Thankyou so so much😇

I couldn't study this chapter last year due to corona virus I couldn't go to school and i missed everything now I m in 8th and my and day after tomorrow I have my unit test of this chapter...... Thank u mam ❤❤
have best in test
It was really interesting and the way you teached is also understandable...
Thank you 😁mam
Vedantu does not post many videos of social science. visit magnet brain to get those, really good explanations not saying that vedantu is bad .just saying that both are da best!!! 😄
yup
Yes ......
Me thinking why do people study one day before their exam and then I realize that I am also studying for my tomorrow's exam
😂😂😂😂😂😂😂😂
Ya
I recently did this😅😅
😇😃😝
There see one day before exam for their revise 😂😂 not they are reading first time
And I am seeing it one day after exam 😃
Stop it at 32:50 Lmao 😂 anyways thnks a lot ma'am 🙏 u teach really well ... I am studying science from u as my final terms are coming soon😊😊
Are you an army too?💜

What is it I didn't get it
Mam one doubt in the diagram of magnetic effects that diagram is there of which compass... Directions' compass or maths compass that we use for geometry?
Directions one because the needle has a tiny magnet which deflects when an another magnet is placed or with an electric conductor which has current flown through it
Hello mam
mam this ch is for class 8 but i am in class 7 , but when i searched for class 7 there isn't any video of this ch so i am studying this ... is it ok na ?
its fine cause 7 and 8th have the same thing the only diffrence is that 8 has a little bit more portion
Mam is induction do heating effect of electric current
mamm, i have a doubt. if we connect five cells and one bulb in a circuit then what would happen
I dont know also
Ma'am please tell when the switch is in o position which type of circuit is it ?? Is it open circuit I think so....
Please tell ma'am
21:40 class 8th chapter 14 starts
I got it!
Thanks alot mam :-)

@@jaishreeshyamji5455 dear,
Nabamita miss is not in Vednatu now.
She is in Unacademy, you can ask her.. When she come live in tht channel...
😊have a nice day 🌹❤
When current flows through a circuit it produces magnetic field around the circuit it is called magnetic Effect of Current.
It produces because of resistance of conductor.
@@VShiksha21 Thank you so much!
21:41 Starts for 8th class
Mam muje magnetic effect of electricity nhi smaj aya
thank you for teaching
You know what, every teacher says that i will solve your doubt in the comments but no one does😔
Please let me help you
Pls do separate for class 8
Yess
Yes
Maam can u please tell that why MCB or electric fuses are not used in a circuit containing electric cells?
Thank you so much for this Ma'am, This helped me a lot.☺🙏
Also teach applications of the heating effect of electric current and their important electrical appliances by step by step
Thanks mam the way you teach is awesome I understand whole chapter clearly

I haven't understand magnetic electric can you explain me clearly
Affan 😃😃☝️
Yes mam can t explain clear
Watch it again 😂
@narasimha Murty An electro magnet is a insulating wire around a magnet which causes a magnetic pull
The reason why people use an electromagnet in industries is because it is more powerful than a normal magnet
Legend's are those who will become something by just studying form books and youtube 👍👍👍👍🔥🔥🔥

@@punamsingh2851 no

Mam 😟 you didn't explain magnatic effact of electric circuite very well...i couldn't understand what actully magnatic effact of electric circuit is..and how wires acts like magnet...how magnetic charge generates? And why compass needle deflects.......
15:42 mam you also didn't explain that why iron nail start attracting metalic substance when the circuit is closed , why it's happens?
Magnetic Effect- Suppose I have a circuit that is closed, so when we will put a magnetic compass near the circuit you'll see that the needle is getting attracted to the circuit and when we will open the circuit the needle comes to it's original position
@@aparajitasinghaadhyasingh1070many thanks to you that you try to explain me but all the things which you are telling to me is already cleared to me! My exact question is that....how magnetic effect generates...what happens in the circuit so that it starts behaving as if it is a magnet...i know when we coil a metalic wire in anything and attach it to a circuit it will behave lika a magnet but i wanna know how it's happens..
Magnetic effect of current is generated when electric current flows through a wire
All right
@@RajniSharma-mq7vw it's my pleasure
Ma'am you and Vedantu is the teaching class and your are the best teacher😍😍
Yes write
PathA h kis way me best h 🤣

maam me bhoot chadhgaya
Can u teach 7thand 8th separately instead of Wasting time
lol
this is not wasting time
@@swiftcone9990 it is for me ok
@@jacksonbodra6450 🤨🤨😏
Mam what is conductor and insulator? Please reply.
watch 12:43 u wll undersdnd
Conductor helps electricity to pass while insulator can't allow electricity to pass
after hearing what people says (legends are watching a day before their exam) I think I am ultra legend because I am watching it 1 hour before my exam at 2x speed
Who is watching this is another exam 3rd March 2021 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
Mam you are a good teacher, thanks to teach me chemical effects of electric current 👍🏼I really like vedantu
Legends believe in comments
Best explaination ❤️❤️❤️❤️❤️❤️❤️
Today is my exam and maybe I got better marks 😀😀😀
Hiw much mark you have got
Hiw much mark you have got
Thanks a lot...
Urmmmm
@Cricket Vines bikini dresses means. ..
Mam I have doubt that examples of magnetic and heating effect of current plz
Magnetic effect is that compass activity that mam shown and heating effect can be seen in a bulb
Hi
If there is a battery in the phone so it's also called battery. But there is only one battery in the phone. So we have to call it also cell.

Ma'am if liquid can produce electricity then why in the first 3 diagram battery was used ??
Liquid is not producing electricity it is good conductor of electricity my baccha....
@@seemavibhute3164 exactly
electrolyte is a liquid which conducts electricity and undergoes decomposition and electrolyte is mainly the salt solution of the desiresd metal

The person is legend who is seeing video simultaneously before examone day or 3,4 hours 😂
# shiksha , Mam I didn't understand the symbol defination of Switch part of class 7.
Just saw your videos related to the topics and revision done.. You are great ma'am.. THIS HELPED ME A TON . TYSM
I felt too much good when I listen to mam that I immediately subscribe and like the channel
In my school book something about cartridge fuse and MCB(miniature circuit breaker)use is also given.....do ma’am can u explain me that
@weirdo !! weirdo!!
@weirdo !! overloading is when current is exceeding the limit and this is where fuses come in handy
Short circuit is when a live wire (a wire with current) is connected with a neutral or earth wire (a wire with no current passing through it) creates a type of reaction called a short circuit
You are reading ncert class 7 book of science
Catridge fuses were the fuses which were used earlier in circuit but we had to replace them when they melts thus, nowadays mcb's are there which are the fuses that can be easily turned on and off and no need to replace them as well
really i am the legendry person who is watching this video before the exam 😎😎😎
