Current electricity Electric current Rate of flow of charge through any cross sectional area of a conductor. Electric current is scalar. S.l. unit is ampere or columb per second Instantaneous current I ins. Is dq/dt. Average current Total amount of charge /total time Direction of current is opposite to direction of electrons. Current density Vector quantity Rate of current per unit area J=I/A Direction of current density as same of flow of charge or current S.i. unit is ampere per metre. Drift velocity In electrostatics net electric field is zero but in current electricity net electric field is not equals to zero. In the absence of electric field ,electron move in random direction due to thermal energy.
Some tricks to rem the formula :- 1. Current Density:- I = JA ( Say like this wo ayi aur tu JAAAA( ur that frnd 😂) i.e i = JAAA. ) 2. Drift Velocity :- I = Vena ( Say like this I = Vena didi ) Vina is name :) 3. Ohm's law in vector form :- J = sigma.E ( Jaggu ki sigma GerEEE ) 4. Temp. Coefficient of Resistance : - Simple R2 = R1( 1 + alpha .Change in Temp( T2 - T1) ). Keep manipulating it just simply rem this don't run for formual for alpha, change in temp. 5. Electric Power : P = V.I ( Be confident with just ohm's law V = IR read the quesn and put the formula acc. to it ) , Units : 1HP = 746W, 1KW = 1000W. 6. Kirchoff's law :- 1st jxn rule : Total current ayi = Total current gayi , 2nd loop Law for voltage ; very easy just see the dirxn from current and start writing eqn VA + IR + E = VB ( find VA - VB) For resistance always write (+) from the dirxn the current is flowing then (-) and for battery big terminal ( +ve ) and small terminal (-ve) look for dirxn of current in this case too. 7. Wheatsone Bridge : R1/R2 = R3/R4 RATIO SAME HOGA THEN TREAT LIKE NORMAL CIRCUIT PROBLEM OR IF RATIO IS NOT EQUAL THEN, SUPPOSE R3 = R4.R1/R2 THEN, WE WILL HAVE EQUAL RATIO AND THEN SOLVE THE CIRCUIT. Hope it helps kinda summary :)) Good luck for phy exam be calm and chill 😊 😊. You will do great
M 2023-2024 vale batch ka hu or m sbhi chote bhai bhn ko ek hi chiz bolunga m pure sall nhi phada tha or m physics s bhot drta tha lekin is bhai ke lecture mene bas last k 3 din dekhe the paper s phle or mere physics m 79/100 marks h toh faida isi m h bas is bhai s ohado m pura you tube chan chuka tha physics ka koi dar nikale lekin yeah best h 😂❤❤❤❤
Itne sare formulas hein derivations hei concepts hein, theory hein itna sab 3 din mein kabhi bhi tum yad nahi kar payoge aur toh aur tough qn bhi practice karna padega kyunki boards tough qns bhi puchta hei ,3 din mein kabhi bhi 79 toh Kya passing marks bhi naa ayein delete your comment right now don't misguide people or else they will not study for boards and will do it at last moment and will score bad marks in boards and listen if you also study physical education at last end you will fail in it because literally bohot kuch yad rakhne ke liye hei physical education mein
Bhaiya , you're doing hard work for us and you're the best teacher 🎉 I understand every thing very well and all concept are clear ❤ , Thank you so much Zaki bhaiya 💯💯💯💯💯💯💯💯
Sir you are explaining things too fast in this video. I came here because the video time was the shortest. But I have to keep pausing every second just to understand what you are saying. And please don't put PYQs in your title, because you aren't even solving them. Any youtube can put them in the description of the video and say that the video contains PYQs.
Hlo bhaiya mene aap ki video abhi dhekni start kre h ye only for cbse k liye h ya neet aaspirent bhi dhek skte h kya?___ plss reply Krna ya fr koi video m bta dena.........
Thank u so much sir for this session . Kal mara exam hai this video is very helpful for us and mainly for whom which is not going to school and can't purchase any batch thank u so much sir ji ❤❤😊😊😊😊😊
Sir please har ek chapters ke numericals wali videos bana dijiye jisme boards level ke bahot saare questions honge case study, mcqs,and numericals wale

Current electricity
Electric current
Rate of flow of charge through any cross sectional area of a conductor.
Electric current is scalar.
S.l. unit is ampere or columb per second
Instantaneous current
I ins. Is dq/dt.
Average current
Total amount of charge /total time
Direction of current is opposite to direction of electrons.
Current density
Vector quantity
Rate of current per unit area
J=I/A
Direction of current density as same of flow of charge or current
S.i. unit is ampere per metre.
Drift velocity

Thx
Engineer can do everything except engineering was epic😂😂😂❤️
@@Pavni077 it's not epic it's very sad that engineer's don't get the job they deserve after doing so much hard work

Bhai 3 din mein physics ki part1 and 2 kaise cover ho sakti h? + Revision ke liye atleast 3 din hone chahiye. Jhoot bol rhe ho kya🤷🏻♀️
Board 😂
He's lying for likes
Itne sare formulas hein derivations hei concepts hein, theory hein itna sab 3 din mein kabhi bhi tum yad nahi kar payoge aur toh aur tough qn bhi practice karna padega kyunki boards tough qns bhi puchta hei ,3 din mein kabhi bhi 79 toh Kya passing marks bhi naa ayein delete your comment right now don't misguide people or else they will not study for boards and will do it at last moment and will score bad marks in boards and listen if you also study physical education at last end you will fail in it because literally bohot kuch yad rakhne ke liye hei physical education mein

The study of physics which deals with the charges in static condition is called electrostatics
Intro of the video 💀💀
Thanks sir for the amazing lecture❤
Bhaiya kirchhoff law ka specific video nhi hai
Ohm Butt swaha 😅😂
No one baki at the place of zaki...(Bhaiya)...❤️🤞❤️ love u...😍
Electrostatic which deals charge is in rest
I think I use to headphones 🎧
Video starts at 3:25
7:55 is it absence of Enet or presence of E net. Because electricity field is there now?
Bhaiya , you're doing hard work for us and you're the best teacher 🎉 I understand every thing very well and all concept are clear ❤ , Thank you so much Zaki bhaiya 💯💯💯💯💯💯💯💯
Thank you ❤❤❤😊😊😊
Really sorry your explanation is outstanding
4:44 per Mai to ladaki hu bhaiya 😅😂
27:30 Spacial hai 😂
Electrostatics -charge at rest
Sir, Physics ka sample paper solve kra do
Sor ap NCERT solutions ke questions bhi solve karate hai?
Om but swaha 😊
Sir you are explaining things too fast in this video. I came here because the video time was the shortest. But I have to keep pausing every second just to understand what you are saying. And please don't put PYQs in your title, because you aren't even solving them. Any youtube can put them in the description of the video and say that the video contains PYQs.
Zaki bhaiya bta do kon se book leni hai......?
Abhi tuk nhi pata chala
Video mein cut issue boht jayada hai bhaiyaa please in series

Bhaiya u are the best teacher of physics ❤️
Very good explanation 😊😊❤❤
thnks bhaiya was waiting for that
bhaiya is this sufficient for competitive exam ?
or you are teaching as cbse boards reduced syllabus point of view ?
no it's not sufficient for competitive
