15:30 : for the curious minds The reason for a high resistance shunt in a voltmeter was to reduce the amount of current through the galvanometer since it can only handle smaller values of current. and the reason for low resistance shunt in a ammeter is to allow maximum flow of current through it and not the galvanometer again, because it will get fused.
My learning :- *niab =c theta *nba/c is galvanometer sensitivity. *for ideal ammeter the resistance is 0. *( I°- Ig ) S= Ig×Rg , for converting into galvanometer to ammeter. * For galvanometer to voltmeter V°= Ig(Rg+S).

i subscribed the channel when there were around 170k subs and now they are 222k ❤...Keep it up Sir .....Your platform is gonna to get a super wave in few months 🤞🏻🔥
sir jee mains ka result nikalne ke baad sare 99 percentile wale bache joh aapse padhe hai unse kuch interaction ka session rakhiyega .aur physics 100 ke sath zoom meeting maja ayega
I have never studied before this topic even during my 12th😂but you made it so easy like I started to solve all the questions correct with just the knowledge you gave in the start of the video😅....thank you so mch sir ❤
Sir one request.. can u take a few live sessions and discuss with us these 503 subtopic,like only their formulae, I think this will revision way more effective.. thank you
@@mohitgoenka99 Sir please take those sessions in like a unit wise manner [mod. phys. , SC , commn. , EMW] [ Electrodynamics ] [Waves and Optics] [Mechanics] [Basic like unit dimensions error instruments (all) ] [ Mechanics 2 with fluids solids shm ] [Heat and thermo] In this way it would be very helpful I'm just requesting sir 😅❤️, Keep it slow if u want coz we know you are handling alot of things on your shoes , and the amount of hardwork you are putting in makes me Push myself too even half an hour more ❤️❤️❤️ MOHIT SIR PROUD STUDENT ❤️
Ammeter when shunt rs connected to prallel to galvanometer v across galvanomter and rg same igrg=(io-ig)rs volmeter when shunt rs connected in series to galvnometer vo=ig(rs+rg)
Thank u so much sir I have no words to explain how you taught me this topic as I was struggling with this topic and u taught it like it was nothing ❤❤❤❤❤❤❤
I'm actually alot thankful to you sir... Learnt number of key concepts from you that i wasn't able to understand at coaching, lots of love and respect for you. ❤
I followed each and every line of this video strictly...and trust mae ki maine har question krlia ....very easy question..thank you sir i have my exam on 12 of this chapter n I m sure ki mai acha krluga
For self review Q4 already done in notes same type of question Q5 silly 😜 mistake add Resistanceof 1st range voltmeter Q6 do it yourself 😂😂the range is not from 0to 10 its 1.0
thnx sir 4 qs of this topic came up in my sunday aits , i was not able to do that and litreally all of my frndz did those 4 qs , i was demotivated , but after this video i was able to solve my aits question very easily even in 30 sec thank u so much
5:28 torque due to magnetic field is balanced by spring torque (restoring torque) due to this needle is at rest and reading is obtained 9:50 current at which there is full deflection = Ig 28:15 good question 33:40 nice 39:50 ROUNDING OFF 5.55 = 6!
Sir these videos are just like gold. I'm thankful that i came to know about your channel on time and not wasting my remaining time on one shots. Thank you ❤
before this session - NTA please do not give me the question of Galvo , Amm , Volt ........ after this session - I am praying to god so that NTA should atleast 2 questions from this topic.........tnx sir
15:51(pyq)20:50(pyq),24:12(pyq),34:53(pyq: v gud ques.... concept involved k(theta)=NIAB,+ for ammeter (I-Ig)S=Ig Rg , and also...5.5 ka round off=6..agar odd hai 5 ke piche....then odd+1 krke round off hota h)
Remember while studying Galvanometer you get gas . GAS P G: GALVANOMETER TO AMMETER YOU ADD SHUNT( SMALL RESISTANCE) IN PARALLEL. NOW WE CAN REVERSE IT FOR VOLTMETER GALVANOMETER TO AMMETER YOU REQUIRE LARGE RESISTANCE IN SERIES WITH CIRCUIT.😢
Thank you so much dear sir 🙏.. I found this channel two days ago and finding ur explanation very amazing.. I scored 62 percentile in physics in attempt 1..can I increase it to 99..if yes then kindly tell me how to study accordingly 🙏
@@varad9334 Yes it is possible just cmplt 3 blocks of 20 days checklist but with full determination have faith on yourself. Ye sochke kro ki agr tum nhi kr skte to koi nhi karskta. Still u hv time.
*PERSONAL NOTE* revise the formula of the Galvanometer NIAB=C(theta) in which NAB/C is galvanometer sensitivity revise 4th pyq note from the video 0.1 can be negligible for 5,6,7... but it is not negligible for 1 or 2. *AFTER REVISION NOTE* REVISE Q3 28:48
Sir plz make a short video about figure of merit it was asked in 25 june shift 2.. and Sir one more request that if possible plz provide session notes with solutions along with ques for the chapter wise pyqs for 2022..🙏
Thank you so much sir❤ I had given a lot of mock test, many question came from this topic, but I had lefted that all may be just bcz of fearness. But after watching this I again go and reattempt, that reallyy.... Tooo... Easy... Tq sir for making hardest to easiest the whole physics day-per-day. just some month ago, I was really very weak in physics and was getting 25-30 marks only but now I am getting 60-70 marks. I know that it is not enough but it is far better than 25-30 marks. ❤
i dont know why i got to know about your channel so late.. it is literally a blessing for me in the last days of preparation of neet. completing vast portions in such less time...grateful!!! thank you so very much sir!!
