Topics covered in this Current Electricity Class 12 lecture by ABJ sir IITD with timestamp:
00:00 - 05:55 Short Circuiting: Short circuit is simply a low-resistance (or zero-resistance) connection between the two conductors supplying electrical power to any circuit. This results in excessive current flow in the power source through the 'short' and may even cause the power source to be destroyed. For a Battery, a Short circuit means joining of both terminals of the battery using a low-resistance wire.
05:55 - 09:35 Open Circuiting: A circuit in which the continuity is broken due to which the electric current can not flow is known as an open circuit. In an open circuit, the current flowing is zero. Thus, no power dissipates from an open circuit.
09:45 - 21:13 Current Electricity Problem 1: In this problem, there is a resistance R connected with a battery of voltage E and internal resistance r. Then, find the current value across resistor R and the potential difference across the battery. Also, find the rate at which chemical energy is consumed and energy lost by the battery itself, and the efficiency of the battery.
21:13 - 29:29 Important points (last problem): Using the results of the last problem, ABJ Sir explains the ideal and non-ideal battery. He draws the graph b/w efficiency and internal resistance, and curve b/w power output and load resistance, and he also derived that for maximum power load resistance should be equal to internal resistance.
29:29 - 39:57 Maximum power across load: The load will consume maximum power when the resistance of the load is equal to internal resistance. ABJ Sir also explains for a fixed power, two values of load resistance are possible and he also derives the relation b/w both resistance using a quadratic equation.
39:59 - 44:50 Current Electricity Problem 2: In this problem, there are two batteries and two resistance according to the given arrangement, and there is a short circuit across both batteries. We have to find the value of the current in each wire.
44:52 - 53:46 Current Electricity Problem 3: In this problem, there are Four batteries and Four resistance according to the given arrangement, and We have to find the current value in each wire. ABJ Sir solved this problem using the concept of a short circuit.
54:06 - 58:02 Rating on the instruments: ABJ Sir explains the meaning of each reading on the electric instruments with the help of examples. In this example, there is a bulb rated with V = 220V and P = 100 W, and we have to find the bulb's resistance.
58:02 - 01:01:19 Example 2 (Rating on the instruments): In this example, if the Potential difference of 110 V is applied across the same bulb ( Last Problem), then what will be the power of this bulb.
01:01:35 - 01:08:27 Kirchoff's Current Law (KCL) or Junction Law: Kirchoff's current law (KCL) states that the algebraic sum of branch currents flowing into and out of a node equals zero. This is an outcome of the principle of the conservation of electric charge. If any new charge enters a node, some charge must exit.
01:08:44 - 01:15:50 Current Electricity Problem 4: Based on the KCL. In this problem, there is a electrical circuit, with three voltage source and 3 resistance, and we have to find the current in each wire.
01:16:00 - 01:27:17 Current Electricity Problem 5: Based on the KCL. In this problem, there is a electrical circuit, with three voltage source and 3 resistance, and we have to find the current in each wire.

Bro solve it as a equation
iR = E - ir
i(R+r) = E
i = E/(R+r)

#askCompetishun sir ive started completing lectures of phy chem and maths per day from youtube (as per praveen timetable of 3 hrs every subject), when should i buy a mock/test series? Right away or in 30 days when some of the chapters are complete (atleast 1or2 from every subject) so that i can again attempt them after 1,7 and 21 days?
At 39:50 both side E should be cancle na sir and one E will remain.
yup it was a mistake
5:12 Sir conventional current always flows opp to movement of electrons but why you considered opp of that over here, you took the direction of current along the movement of electrons as anode is getting oxidised and cathode is getting reduced
sir ye
current electricity ki sheet download kaisai kare ... reply fast plzz
24:46 pai hume is formula ko learn karna hai?
😭😭😭How can I thank you sir😭😭
Sir pls suggest me a book which as I am in class 11 not able to solve cengage and do not have any coaching material
Bro this is an excuse . I also felt same but now I relate many things with these lectures. Also cengage is almost same as reso material.
Just I tell u plz watch complete lectures of that chap then go through with notes then study cengage thoroughly . solve que.
Its all mine experience bro.
Still u want for reso.
Sir resonance sheets 11+12 in telegram u will get stuff.
@@believer9370 thank u very much bro I respect ur opinion and I will definitely follow it
what are you doing right now which college?
53:47 Shouldn't the voltage increase if the battery acts as a source for the 30v battery?
1:15:14 sir if current flows from higher V to lower V why have you shown it flowing in opposite direction?
{if I have a conceptual error, please correct me guys}
Sir can you please start uploading DPPs for JEE Advanced 2020 from today.

Yes
Yes
please can anyone help...at 1:24:52 I took the voltage above the +ve terminal to be 0 and at the lower side to be -100...but i am not able to get the answer that way
Nice explanation sir
Sir can we crack iit by studying seriously for 2021 (I have studied all chapter a bit)
Yep
hey what college are you in ?
Sir plz complete electricity portion of 12 th first.....
🙏🙏🙏🙏🙏
Awesome Explanation 👌
Current ke taraph jane par potential badhata hai, to sir 15;10example me potential E+ir hona chahiye
CAN someone tell me how E-ir / R is equal to E/R+r??? at 13:47
i=(E-ir)/R
Cross multiply
iR = E-ir
iR+ir =E
i(R+r) =E
i=E/(R+r)

Hindi hi bol lo
13:20 current 0 and 0 volt and E-ir and E-ir ke beech kaise flow karsakta hai? Potential diff na hone pe current kaise flow karsakta hai?
44:08
wo explain karne ke liye likha hai wo ek side me same potential hai
Ty sir
Nodal Analysis isi chapter me h n??? Mujhe ni mil raha please help me out
39:30 I think its P=E/4r
Actually sir took E instead of E² in the bracket by mistake therefore it's coming E/4r but it will be E²/4r only

2nd question mai middle bala battery mai. 100 v for lower to higher and -100v for higher to lower kcl bala questions mai
sir series parreal iske baad karana hai
Best ever
18:37
1:01:35 sir kcl ke according no charge is accumulated at the point where more than one resistors is connected.
But sir aapne iss lecture (czcams.com/video/EOo9L_PHVtI/video.html&si=xanFWmf9Tfs1kO5g) ke 1st question jo karaya tha usme to charge carriers accumulate ho rahe the. Ye kaise possible hein? Pls sir explain I am confused.
Kcl junction pe valid hai ur woh tab jab alag alag resistors junction pe ho but us que me woh ek hi resistor me alag alag resistivity ki wajah se kuch charge waha pe accumulate ho skte hai
sir do I need any prerequisite knowledge to start current electricity since I am in class 11
Noi
12:54 sir jaise aap neeche right side to left side gaye to calculate potential , if we apply the same logic oopar , right side 0 tha na ? agar left jaate hai against current , tho potential badta hai by iR . so vo galat kyu hai and why E-ir is the correct answer ?
try again mera sahi aa rha hai tumhara conceptual error hai
44:00 Sir why both the batteries are behaving as loads?
both are behaving like source...and that is ok
@@Competishun okay sir I had a misconception, Thankyou sir
Wrong differentiation at 27:57
Shi h Bhai use chain rule
R d(R+r)^2/ dR = let r+R = x
Ans ---- R ( 2x * d(x)/dr)
Put the values
R(2(R+r) * 1)
{ d(R+r)/dr= 1)
Hence , 2R(R+r)
I hope you are confused in this part as I have typed complete differentiation
Sir
Sir one request to me that do more questions in lecture
Sir how (e-ir) /R = e/R+r
