The examiner was calm and was asking more questions to those who answered correctly. Those who couldn't answer even 1-2 questions were sent back.
All the best!

2. How is p-n junction formed?
3. frequency of AC mains - formula & value.
4. Difference between emf & potential difference?
Thanks
what is the answer to the 3rd one
do u mean the formula for frequency of vibration of a stretched string?(sonometer activity)
@@ojaskulshrestha4236 both
Okayyy hello guys ..these are my questions...
What is least count ?
Kirchoff's law
Difference between focal length and focus ??
Source of X rays ???
How is glass slab different from prism
Formula of the prism
To draw forward bias and reverse biased
What is heat waves
Benefits of gamma rays
What are p-n junction
What is depletion layerr ???
So these are the questions external asked me ... ..good luck everyone
U know
What are the most imp practical
Which they can give us to perform ?
@@OVERRATED_247 if u ask me about practical it's totally depends on the examiner because different examiner different ideas ... But most probably joh joh school me karwaya hai wohi dengee ..aalag se kuch nhi hoga because woh karwaya nahi ... Hume sirf prism meter bridge karwaaya tha school me aur wohi dono aaya tha ..so zyada tension mat lo ... Just focus on viva especially baki school teachers will help u
@@snigdhabharadwaj5381 perform bhi Krna hota h hma ky
@@OVERRATED_247 hume group wise Mila tha ...every experiment ... For meter bridge 3-4 students ..but remember one thing examiner can ask u questions from the experiment .. hota hai kabhi kabhi agar strict examiner aayee toh

Thanks we are ultra legends😂
Ekdam sahi..30min pahle😂
Yup, just 3 hours left. I am scared shitless.
2024 a day before physics practical
30 mins me exam hai and this is the first vid I'm watching as a preparation.lol
konse questions puche?
@@yashranjan9575 mere wale kafi acche external the bas puche aim in life , kisi bhi topic pe 1 min bolna or resistor kya hota hai ohms law kya hai or kuch wahi sab
My practical viva questions. 1.what is knee voltage and Breakdown voltage. 2.depletion layer and potential Barrier
1. the forward voltage at which the flow of the current through the PN junction of the diode increases rapidly is knee voltage
the threshold voltage at which the initiation of breakdown occurs is breakdown voltage
2. The potential difference required to move the electrons through the electric field is called the barrier potential.
@@tanishapahwa thnx
Bass 2 ?
Sir I totally agree with all your Questions
Btw the same questions were asked today in my biology practical exam 😂
Kya??
Had my viva today
Questions my examiner asked me:
Chapter you have prepared:CURRENT ELECTRICITY
1)What is drift velocity?
2)What is emf?
3)What is potential difference?
4)Relation between drift velocity and torque(Relaxation time)?
😊That's it....so glad😁it was easy...
it's not torque..
Just the symbol is same as that of torque.
Toe
It is not torque ,it is average relaxation time
You mean tao right?
It's tau 🤣😂
Today was my praticals...i had fun with external...
He asked me wat is physics actually...i said study of nature and about it...he asked where is your home...what is your marks in 10th...and more...🤣😂🤣😂
Haha 😂😂nice
Hahah same with me and even more😁😆😆😆😆
Bhai mereko kuch nahi ata kya hoga??

Tomorrow is my Physics practical
Darr lag raha hai 😫
Me too
Kaisa raha practical?
My teacher told me to revise all the principles of the experiments.. And for potentiometer, metre their construction and working too.. For optics- definition, types of images formed.. Ac mei she told me to focus on the principle of transformers and mutual induction definition.. And for pn junction the whole chapter .. I would suggest u to look at the one markers of the related chapters like ac , optics etc from SL arora
Noted.
Mera practical ho gya aaj
Bohat best ho gya sir ne good bola 😎😎😎
One tip -- mostly they ask only practical question
Who are the legends watching now before 5 hrs🫡
Ultra Pro max legends watch after Practical 👍👍
Pratical ke baad kya fayda dekhne ka😅
Life is too short to argue just say "sorry sir" 😂
my practical questions
transformer
types of transformer
no . of turns in step up and step down transformer
principle of transformer
1. Transformer is a device that transfers energy from one electrical circuit to other by increasing or decreasing the voltage
2. a. step up transformer
b. step down transformer
3. a.no. of turns in step up transformer are more in secondary coil than primary
b. no of turns in step down transformer are more in primary coil than secondary
4. Electromagnetic induction- principle
@@tanishapahwa hey! Transformer to mutual induction principal pr based hota h

1. Draw diagram of LED. In which biasing is it connected? (we had an activity involving LED this is why he asked even though it is deleted)
2. What is Barrier Potential?
3. Why Convex mirrors are used in rear view mirror ?
4. Explain Kirchoff loop rule and on what principle does it work ?
5. What happens to resistivity of metal and semiconductor on increasing the temperature ?
