Sir charging and discharging of capacitors me "To verify that 63% charge is stored in a capacitor in a R-C
circuit at its time constant and 63% charge remains when
capacitor is discharged and hence plot a graph between
voltage and time" wala experiment karna compulsory h
Sir like nhi jawab dedo
It's depends on what your teacher directed
Capacitor ka charging prove karna to compulsory hi lagta hai
Bro kiya to reply check kro
Bro you used 2 resistors in the working model but in the project there is only one used so how should i do it . Please suggest....
In project pdf it's not working model it's experimental setup we do in lab to get readings
Op Bolte
Bhai kya ye 2022 2023 ke syllabus me hai
You slay
❤️
Thankyou for you feedback
Sir what is the time constant
Sir can you please suggest a working model either base on electrostatic charges and field or electrostatic potential and capacitance
make a gold leaf electroscope but with aluminum instead
Interested physics 🥰
Sir isa explain par bhi video bano
❤️❤️❤️❤️❤️ bahut khub 👍
Thanku for you feedback
Plz make a modal in AC generator🙏🙏
Ok.......I will try
Sir ye Jo apne project file di hai ye humare book me khi nhi hai aur na hi 63% wala concept aur na hi derivation
Bhaiya, mere pass Resistance 1200 ohm ka hai aur Capacitor 1000uF 35V ka hai toh 9V battery se charging or discharging ho jayega na?
Yes, you can use thses components
Love from prayagraj 🤩 ❤ 💕 💖 💗
Yes prayagraj op
Hey senior 😅
hn toh
The worst place ever I saw in my entire life #city of hatred
Allahabad
Can you plz plz give me the project file for this working model in pdf/.docx format?
It will help me a lot
You can easily get it from any website......just search it on Google
Sir can I just do the project on
AIM:- Showing the charging and discharging of capacitor in a RC circuit..??
Yes, both are same
Thank you sir
@@knowledgecycle can we use 35v 4700uf? then how much resistance is required
35V capacitor mean it can charge maximum up to 35V but since the battery is just 9V so the capacitor will charge just -to 9V
You can use 1k ohm Resistance it's enough
@@knowledgecycle thank you so much it helped a lot
Bhaiya ye Jo aapne iske saath PDF diya tha project ka agr usme ham same ye waala circuit model bana denge Jo aapne banaya hai to marks katenge to nhi na ..... Kyuki project waale pdf me thoda alag model hai
Many students used it with that model......but I will suggest you to consult with you subject teacher
@@knowledgecycle ohk bhaiya thankyou for clearing my doubt ..... Because in the procedure topic of this pdf it was a different type of model .... Thankyou ❣️
Bro which wire(red) using while solding them ?plz tell quickly
Connecting Wires dukan pr bolo mil jayega
It is necessary to sold thw wire can i just tape it
You can just tape it
@@knowledgecycle ok thanks
Sir thank u for the video. But please try to speak in english or you give english subtitles for us to understand sir.
thanks for your feedback....... actually 90%+ viewers are native that's why I can't make videos in English
but for those who don't understand Hindi will definitely add English subtitles
Sir is it necessary to use the solding wire
No not that necessary........just bind the wire
Soldering is just to make it more and more strong
Can you please tell me i don't have soldering iron so what can i use
Can I use tape
Yes after binding the wires to each other you can apply tape over there
ye kis chapter pe based hai model??? please reply fast
Charging and discharging of capacitor ke phenomenon pe based h
@@knowledgecycle thanks
Is this topic comes in CBSE 12th board in 2020-21
Plz reply me as soon as possible
Yes
Agr hm Jis value k resistance, capacitor etc instruments Apne use kiye h usse zyada ya km value k use kre to model work krega
ha jarur karega bas jyda difference nahi hona chahiye.........maai apko suggest krunga ki appp ek barr rough connection kar ke try kar le phir usko cardboard me fit kare
@@knowledgecycle okh thank you so much😊
S👍👍👍👍👍
Thanku for your feedback
Can you explain its wiring again??
Plz download the circuit diagram and do the connection accordingly

Can we use led from 1.5V -3V
Yes
SIR CAN WE DO THE SOLDING WITHOUT THE CONNECTING WIRES OF BLACK N RED
You can use any connecting wire
Another way to make yeh hone chahiye
Humble respected to you hone chahiye
bhaiya can i use the capicitor of 16 volt 2200uf ? will it work with 1000ohm resistance
Yes
Bhaiya 1000 ohm resistance or 1 ohm resistance
Plz reply fast if possible i am in shop for purchasing i asked bhaiya but 1000 ohm resistance not available
1k ohm means 1000ohm
Can we use 25 wolt capacitor
Yes you can but don't forget to use the resistance
Bro
Resistance q use kiya hai
Uska kya use hai
And tell me something more about it
So that I represent myself well in front of examiner
Bro hamara jo battery h wo 9V ki hai aur hamne jo LED bulb liya hai wo approx 1.5V ki hai. Yadi hum bulb ko direct battery se connect kar denge to wo kuchh hi seconds me fuse ho jayega...... that's why we have used Resistance.......I hope you understand.......for more details just read the description box
I hope I am able to help you
@@knowledgecycle yes
Thanks
Sir where to find capacitor,
Mujhe mil nahi rha kahi bhi
Sir agar solding iron nai ho to kya wiring n Kr skte h please reply
Nahi app aise hi wire co connect kr do tb bhi work krega
Bhai ye bina resistor ke nahi kam karega kya?
Nahi bhai kyu ki battery 9V ki hai....aur bulb 1.5V ka
Yadi 1.5 V ki battery use kroge to resistor ka jarurat nahi h
Sir my charging led isn't turning off, and discharging led isn't not glowing, rechecked the circuit
Send me the images of your model on my Instagram @Ankur_k_c
@@knowledgecycle I've dm-ed you on Instagram
@@surjitroy2616 is it working bro, mine not
@@knowledgecycle bhaiya facing same problem m i am making this project since a week and project submition is on monday
@@tarunasharma2267 konse school se ho? mera bhi same monday ko h VIVA, mai aaj ya kal banaunga
agar nhi bana to paise dekar dukaan se banwaunga
Bro 1000 mirco farad 25v mila hai chalega
Aur resistor 820ohm hai will it work
Yes
Iam sure yaha pe zayada tar log apne boards ke liye model banane aaye h
Why not bro
sir kya capacitor 1000uf of 25V ka use kar sakte hai
yes but make sure you use 1k resistance with that otherwise the LED will be converted in to ashes
Bro can you give mai information about cardboard or sheet from where I should buy cuz I don't know anything humble request 🙏
don't worry bro it's just a exam pad.........go to stationary and just ask for the exam pad and take the thinner one
or you can cut a square shape from any cartoon box(cardboard box) like laptop box or box in which flipkart or amazone send their peoduct
Okk thank u so much 💖💖
Bhai resistance bhot important hai kya ise circuit mai?
Yes........ resistor ke Bina bulb fuse hi jayega
Can we use 470 peco farade capacitor??
470 micro farad
What if we don't have iron how do we connect the wires then
Just bind the wire tightly so that they won't loose
Charging led glow karna band nhi kr rhi. What could be the problem?
Text me on instagram along with the images of front and back connection

@@knowledgecycle thank you sir, mil gaya
How you made the circuit diagram...? Please reply me...
What is tough in it.......it is just a simple diagram with two circuit
You can download the circuit diagram link In the description
@@knowledgecycle sir, I have to made the another circuit diagram for ppt... I will use the circuit diagram in ppt... But Im confused that how I made it... I have no computer or laptop.. Just having a smartphone..
@@j.b.2693 ohhk thats the isssue...... don'tworry I have also made it on smartphone
Application name- PicsArt
@@knowledgecycle ok Sir. Thank you very much for giving me time and reply... now I try to make it....
You're welcome 😊.........good luck 👍
Kya hum iss model ko 2022-23 me bana sakte hai ?
App 2025 me bhi bana skte ho
Joke a side, ha bana skte hai koi issue nahi hai
Bro I feel like the pdf is different from the Model you made because we didnt use multimeter while making ghe model
Pls reply as soon as you can
This model is just to demonstrate the concept of charging and discharging of capacitors in practical (real) life
And the pdf is fully based on its principal and precise experiment with mathematical calculation and all
For more clearance you can consult with your subject teacher
@@knowledgecycle ohh ok thankyou for this
@@knowledgecycle and I have one more doubt I made this project that time I had to use 2 resistance in charging circuit because mera Bulb fuse ho jaa raha tha
So is Doing that ok?
@@knowledgecycle reply kar dijiye jaldi se mujhe submit karna hai
Can this 1000uf capacitor work on dc current???
Here we have DC current in circuit because we have used DC battery
@@knowledgecycle but capacitor works only on ac current...
Then how this model working pls tell??
Discharging a capacitor
Why should a capacitor discharge? Imagine the capacitor with all its charges is kept inside a bag and tied at two open ends (open-circuit).
The positive charges on one plate are attracted strongly to the electrons on the other plate, and the electric field is strong and uniform between the opposite charges on the plates. The opposite charges on either plate seem to hold each other tightly. The field is not so strong to cause the electrons to cross the gap and reunite with the positive charges.
There is a fringe field at both ends ready to burst the bag, but the open circuit does not allow charge flow in the external circuit. The electric fields of surface charges which move onto the wires from both the plates and the fringe field will, during the initial transient when the wires are attached to the plates, combine to make the resultant electric field in the wires, zero. The fringe field is different from the field between the capacitor plates.
When the charged capacitor is short-circuited using a wire, the effect is to open the tied ends of the bag and the charges are released. The fringe field causes the initial crucial release of charges for further flow of the charges….and development of surface charges that will enable the charges to flow around the wire, and neutralize each other. After all the charges on the plates are neutralized, the circuit attains a state of static equilibrium, a natural relaxed state of equilibrium and we say the capacitor is discharged.
Electrostatics and circuits belong to one science not two. To learn how a capacitor charges and discharges and the origin and role of the fringe field in the circuit process it is instructive to understand Current, the conduction process and Voltage at the fundamental level as in the following two videos:
i. th-cam.com/video/REsWdd76qxc/w-d-xo.html and
ii. th-cam.com/video/8BQM_xw2Rfo/w-d-xo.html
It is not possible in this post to discuss in more detail the formation of the fringe field when a capacitor is charged and discharged.
The last frame References in video #1 lists textbooks 3 and 4 which discuss these topics in more detail using a unified approach and provide an intuitive understanding of discharging a capacitor with the help of sequential diagrams.
Charging a capacitor
"The voltage across a capacitor cannot change instantaneously" is a statement one finds often in textbooks on circuit theory which discuss the application of a step voltage to an RC circuit.
Most students memorise and apply this in circuits without understanding the physical processes involved.
It will be useful to learn the operation of charging a capacitor using a unified approach to electrostatics and circuits.
It is not possible in this post to discuss the charging of an uncharged capacitor. During the first few nanoseconds after switch ON, while the surface charges arrange themselves, there is no electric field E_cap and fringe field because there is no initial charge on its plates; it is as though the capacitor was not there - as though there were a continuous wire with no break in it.
The last frame References in video #1 lists two textbooks 3 and 4 which discuss in detail with a series of diagrams the physical processes in charging a capacitor without and with a resistor (RC circuit).
Nice info sir...... it will work alot for the students
