sir m Pakistani hun or m 2nd year medical ki student hun ... apky lectures bht bht achy hen I'm impressed .. plz kya ap koi physics achi books bta day self study k Lea ... plzz
I am an indian but you can trust me ( just kidding ) ... Buy HC verma .. it is short and best ... you can even download it here : HC VERMA part 1 : drive.google.com/file/d/0B38bwaQZtmsSOW15QlE1dWlraHc/view?usp=drive_web Couldnt find part 2 .. but take a look. Its by a very famous professor and its very small and nice to read.. everything explained ..
sir i have a doubt. you said that the longer the main wires goes from town to village, villagers will get less voltage than town. but how can it possible?the rural and urban peoples should get the same amount of voltage as they are in parallel. please reply!!!
Thank you so much sir! You have no idea how hard it has been for me to understand the exact difference between emf and terminal potential difference. It's amazing how clear and precise you make our concepts clear. No disrespect to any other teachers, but they should truly put more effort in making students understand.
sir at 35:30 you wrote the equation as V = E - ir and deduced the result that when load increases current increases and thus voltage decreases but By applying ohm's law that states 'v' is directly proportional to ' i ' which contradicts your statement... the basic question is that, is R constant for that can we apply ohms law there to get linear ralationship between the two or not? waiting for your rply...
here V is terminal Voltage and small r is internal resistance , internal resistance present when we say about EMF but that V is directly proportional to R that is external resistance
here V is the voltage of cell.... if a cell is connected in a circuit but no current is flowing in that circuit... you can not say that voltage of battery is zero... here V is battery voltage or cell voltage
Sir aapne bola tha ki zyada load hone ki wajah se voltage Kam ho zayegi aur sare loads ki voltage same ho zayegi par Aap bol rhe the ki village me wires lambi hone ki wajah voltage Kam ho zati h to aur urban areas me jayada hoti h par according to you all the loads have same voltage but why there is difference in village and urban area's voltage
pradeep sir do doubt hai 1. agar I=0 karenge to e = 0 kyo nahi hoga 2. Kya most of case terminal PD. 2 times hoga emf kyonki ir = E -ir or, E = 2ir ??? and thnx sir recharging topic include karne k liye kyonki main kie bar apne cell phone ke battery me capacity 3.7 v dekta tha aur input 5v aur main curious tha iske bare me janne ke liye 😄😄😄😄
any one clear my doubt ki household supply m heater on karne se bulb ka bhi pd kam ho raha h to fir jab gaaon m 120 V voltage aaegi to town m 240 V kyun town m bhi kam honi chahiye na
in this equation # V=€- ir u said that when i increases then V decreases when € and r is constant but here V and i have direct relation then also V decreases.... I am littile bit confused.....pls tell🤔🤔🤔🤔
Sir what happens when we are charging and discharging the battery at the same time. current flow in the battery and also the load(eg mobile is working).how can there be two direction.
if the battery is of 3v and i want to charge it faster so if i apply 6v to charge it , then does it charge faster then the potential difference applied of 4v to charge it? please give me the ans.
at 26:04...i love the way u spoke "maine kya kya kardiya hai bhai"...
international Remixes sahi me...bahut cute tha😂😂
Haaaa
Salam sir....a lot of pray I want for u from God that always u happy and long live.....one day I will meet u must...Sahaab from Pakistan
Sr ap apne notes PDF m de dijiye plzz exam m bhut help hogi...
Sr bt I must say your videos are very helpful and sr u r great....😊😊
main bhagwan se dua karunga ki sir aapki umar bahut lambi ho.sir..
sir you developed my interest in physics
Awardable work
nice lectures by nice teacher .
For nice onces

Prateek Chauhan how do you get it do you have for more guide plz tel me
i need class 12 do you have?
Modern's abc
Resnick halliday and Walker is a good book
sir you are more more more...... than my physics teacher
Pranam sir
respected Pradeep kindly also give examples of the concepts u explain,or its use in daily life , it will more clarify the concept
sir i have a doubt. you said that the longer the main wires goes from town to village, villagers will get less voltage than town. but how can it possible?the rural and urban peoples should get the same amount of voltage as they are in parallel. please reply!!!
What a lectue... sir,🤗🤗🤗
Thank u my great sir
Sir then how village power will stabilize?
sir why in some cases V = E +ir when current fiows in opposite direction to that which yu have told in this video

love u sirr .may u live long.
Superb

here V is terminal Voltage and small r is internal resistance , internal resistance present when we say about EMF but that V is directly proportional to R that is external resistance
Sir I have a dout. U said that if current would be zero then E=V but sir V is also equal to IR then V should also become zero?
here V is the voltage of cell.... if a cell is connected in a circuit but no current is flowing in that circuit... you can not say that voltage of battery is zero... here V is battery voltage or cell voltage
Sir aapne bola tha ki zyada load hone ki wajah se voltage Kam ho zayegi aur sare loads ki voltage same ho zayegi par Aap bol rhe the ki village me wires lambi hone ki wajah voltage Kam ho zati h to aur urban areas me jayada hoti h par according to you all the loads have same voltage but why there is difference in village and urban area's voltage
Sir agar current zero ho jayegii toh emf measure kase karenge
At 25:09 how can we write i=V/R.. earlier we were taking it as E/R+r.. are they both equal
pradeep sir do doubt hai 1. agar I=0 karenge to e = 0 kyo nahi hoga 2. Kya most of case terminal PD. 2 times hoga emf kyonki ir = E -ir or, E = 2ir ??? and thnx sir recharging topic include karne k liye kyonki main kie bar apne cell phone ke battery me capacity 3.7 v dekta tha aur input 5v aur main curious tha iske bare me janne ke liye 😄😄😄😄
V=iR hota hai where R=external resistance hota hai not 'r'..:)
Nice lecture sir👍
any one clear my doubt ki household supply m heater on karne se bulb ka bhi pd kam ho raha h to fir jab gaaon m 120 V voltage aaegi to town m 240 V kyun town m bhi kam honi chahiye na
Sir, Can you please write here the appropriate definition of emf that we can write in the examination.?
Sir ..hamare house m to parallel combination hota h .nd parallel m voltage change nhi hoti to sir yhn kese kam ho gyi ...y h smjh n aya sir
Love... you sir
good
V is increased with increasing i in ohms law
so why i decrease with increasing V in terminal potential
in this equation # V=€- ir
u said that when i increases then V decreases when € and r is constant
but here V and i have direct relation then also V decreases....
I am littile bit confused.....pls tell🤔🤔🤔🤔
Nice
Sir will the syllabus be complete before our pre boards. ..
best one
Sir what happens when we are charging and discharging the battery at the same time. current flow in the battery and also the load(eg mobile is working).how can there be two direction.
NICE QUESTION...DID YOU FIND ANSWER?...IF SO,
PLEASE TELL ME THAT ANSWER TOO..
Battery become off no current in the circuit. How to tells v=e
if the battery is of 3v and i want to charge it faster so if i apply 6v to charge it , then does it charge faster then the potential difference applied of 4v to charge it? please give me the ans.
thank you sir
sir many have doubt that if I=0 then V must be 0. Is there is a difference in both currents. reply soon..
IN THIS CASE WE USE TRANSFORMER .Ain't I right ?????????????????
but sir now a days fast chargers was come and thats price was aloso high so they also effect our battries
I mean practically
okay...now...target cell combinations
Me getting back to studies ...
meri body se kam heat nikalti h warna mai patli hoti 😒
"maine kya kya kardia hai bhai" haha :)
Sir kitna achha hota agr ap maths and chem bhi pdhate...
Riya Sharma main maths padhata hu
Right
Riya sharma jii YOU are right
sir you developed my interest in physics
