- In this Physics video in Hindi for class 11 we explained what are significant figures or significant digits and their rules.
Rules :-
1) All the non zero digits are significant digits.
2) All the leading zeroes are insignificant.
3) All the zeroes between non zero digits are significant digits.
4) If the number contains the decimal point, the trailing zeroes are significant figures, otherwise, those are insignificant.

Sir, this is the only video on s.f. which tells with reasons. ... Why digjts are significant or not... Other channels only tell tricks to remember... Wow... This is beautiful to learn conceptually .
Yes wow wow
He is the only man who teaches physics of class 11 and 12 rest are just trying to give you a method to pass competitive exam
You spill truth ❤
Wow!!! Sir you are beauty......💓💓💓💓
Love from pakistan
I want to met u sir
Thanks sir Your channel and light house channel is best for physics.You Make physics very interesting to understand nature.
I have seen many videos on this topic but it is the best amongs them 👍👍
Perfect explanation for my doubts..exactly I need this thing..😍😍😍😍
Sir , aap ne significant figure ko best se best explain kiya hai.
Very nice sir.
☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️
Sir thanks a lot,
In whole you tube no one has explained in such a wonderful and practical way🙏🙏
Very good explaination
But I have 1 question- why 10^24 is not considered as significant figures..??
It doesn't represent the actual value/amount, but it indicates how much the decimal point would be displaced.
I watched many videos and I had many queries in my mind eg, why '0' between non zero digits are significant. But after watching this my all doubts are cleared ..
Thanks sir 😊😊😊..💛🤍💚
Thank you sir now l understand s.f clearly.
Nice sir i clearly understand this concept
Thanks
Very nice sir i am totally surprised at the end of the video when i realized that i am not having problem regarding this .Thankyou so much sir.
Your words are like flowing water that's touch my heart
Great teaching method I absolutely loved it
This is exactly what I want.
Tq sir....💙
Physic ma aysa hi sochana chaia.Thank sir .
You are the best teacher of mine❤️
Most helpful video for me
You are a best teacher of physics sir
Please maths ke videos bhi dale please sir
Thankyou sir for making this video
Ekdam Super !!!!!!!! Sir. You explained which digit is considered significant and why ?
Sir ji you are the gineus
But only one thing he is lacking and that is he has not made video for every concept of class 11 and 12
If sir did so then I bet you that he will be much more better than pw
i have seen soo many videos to get concept of S.F...but explaind clearly but after watching ur class concept undstood very clearly thanku soo much
Thanks sir
You made me love physics.......
Please keep uploading such interesting videos
Sir plzz chemistry ke liye koi ap jaisa hi teacher RUclips pe btayiye 🙏🙏
Alakh pandey
Thank you sir .. your vedio helps me a lot
Limiting reactant p video banyn.....
Thanks sir.....you are great
What is the significant number of 12eggs ?
@@thefallingapple1145 No, it's 2, there are no trailing zeros and decimal point in 12
You are a great sir
How many significant figure in :(a) speed of light .
(b)0.0000
Thanks sir
BEST EXPLANATION EVER ON THIS TOPIC
Thanks sir for all videos
Outstanding sir 😊😊

Excellent sir, lots of respect from #physicistskmfindiatv
Sir pls laws of motion pe shru se last tak bana do bhot problem a rhi h numerical solve nahi ho par rhe
Pls
The majority of physics texts composed before 1980 do not include significant figure rules.The apparent lack of significant figure rules in physics texts in the first half of the 20th century is most likely due to the popularity of the slide rule. The slide rule is a device that allows the user to perform a calculation (multiplication, division, square root, etc.) for two values by sliding a scaled ruler. The number of significant figures in the computed answer is limited by the precision of the ruler, typically to three digits. In the preface to the introductory physics text Physics in Two Volumes published in 1974,26 Donald Ivey explains as much: “The numbers are invented and I can invent them to the degree of accuracy I please. In general I shall use simple numbers, so that calculations will not be messy, and the numbers are to be assumed as exact, unless otherwise indicated. In general, calculations should be carried out with slide rule accuracy, and answers will be given to three figures.” As the slide rule limits the precision of calculations, this eliminates the need for the significant figure rules in solving textbook problems. Moreover, this practice of giving answers to three figures is still carried out in modern texts,and may be a remnant of the slide rule era. The explosion of significant figure rules in physics texts in the 1980s is almost certainly due to the widespread use of the calculator. Texts that mention the slide rule do not have a section devoted to significant figures ,while texts that mention the calculator do have a significant figures section. In Sears and Zemansky’s popular text University Physics, the authors remark in the 1982 edition,30 “You may do the arithmetic with a calculator having a display with five to 10 digits. But you should not give a 10-digit answer for a calculation using numbers with three significant figures. To do so is not only unnecessary but it is also genuinely wrong because it misrepresents the precision of the results.” However, in the 1970 edition28 the authors have the opposite problem. In 1970 they need to remind students to give more precision, and in one particular problem they remark, “[The] computation must be carried out to four significant figures, which is beyond the precision of an ordinary slide rule and requires the use of four-place logarithms.” Thus, the introduction of the significant figure rules into physics texts is most likely a response to careless students writing down the 10 digits shown on their calculator.
Thank you......
How did you obtain this information?
Sir g best
Sir wow what a video
Good work..
Very nice 👍 explanation... Maza aa gaya
Maza ayya tho iss channel ko subscribe karo jhi

Sir, Book recommendations plzz🙏🙏
Thnku so much its amazing lecture
Thanq sir

Sir I have doubt that leading zeros has to be significant figure I think because , let we have number 0.07km = 70m , if leading zero has no significant tha we can write 0.07km as 0.7km which is equal to 700m , so
Thank you Sir
Wow
Please help me to find out significant figures in
620×10^2
super sir
Is significant shows uncertainty or certainty
Thank sir you are great
11class ke problems ka video banavo please.
sir you are the best. btw which app you use for writting
Very helpful video sir
Really outstand sir. Maja aa gaya
Make the video on internal circuit of a calculator. I am waiting.
I was missing that pleasant background music🥰
Sir g hc varma ke problems bhi karwao plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz you are best teacher as compare to Pakistan's teacher I m from Pakistan
Bhai Pakistan Me bhi hc Verm ka book chalta hai kya
Bhai Pakistan me bhi hc verma ka book chalta hai
Sar mai kya batau Mai is topic video kai din se khoj raha tha ap agle hc verma Ho nahi nahi Un se bhi great
230m you have written S.F 3
It's wrong please 🙏 check it
Plz round off to 2 significant figures of 302.76
Sir, thank you so much. I can understand your lecture properly but I have a problem that I can't find all videos of the first chapter of physics.....please sir send me the link of 11 class physics....dimension and measurement of physical quantity.please sir..........
Thanks sir, this is your new RUclips channel 🥰
Correct 200 to 1 significant figure, please 🙏
12300km me kitane signifikent hoge
Karm kro fal ki chinta Mt kro
🙏🙏🙏🙏🙏
4500kg how many significant figures
Sir aapke dusre video ke compare me ye thda feeka hai, isme aapne practical example leke nahi samjhaya hai, jo aapki khasiyat hai
