In this video we will cover:-
1.(a) Three resistors 1 Ω, 2 Ω, and 3 Ω are combined in series. What is the total resistance of the combination?
(b) If the combination is connected to a battery of emf 12 V and negligible internal resistance, obtain the potential drop across each resistor.
2.Six lead-acid type of secondary cells each of emf 2.0 V and internal resistance 0.015 Ω are joined in series to provide a supply to a resistance of 8.5 Ω. What are the current drawn from the supply and its terminal voltage?
3.A battery of 6V and internal resistance 0.5Ω is joined in parallel with another of 10V and internal resistance 1Ω. The combination sends a current through an external resistor of 12Ω. Find the current through each battery.
4.Determine the current in each branch of the network:
5.In a meter bridge, the balance point is found to be at 39.5cm from the left end A, if an unknown resistor X is in the left gap and a known resistor Y of resistance 12.5Ω is in the right gap. Determine the resistance of X.
6.Determine the balance point of the previous bridge if X & Y are interchanged.
7.In a potentiometer arrangement, a cell of emf 1.25 V gives a balance point at 35.0 cm length of the wire. If the cell is replaced by another cell and the balance point shifts to 63.0 cm, what is the emf of the second cell?

CONCEPT HUA CRYSTAL CLEAR : )
One suggestion mam : While explaining using the mouse(pointer) please use some indicator symbol, because the very tiny dot pointer is not visible in the white background.

[shivangshukla]

Awesome explanation!!!!
School prep from here only ❤️.
Now, I got a problem at 36:49 . The answer must be 0.09 not 0.9.
😜

[TarunKumar-bsjr]

I'm having my exams in next 15 hrs and Now I'm clearing all my doubts here..! Best teacher Hit like if you're a last moment study person😂😂😂

[pallaviyadav]

Mam you are really a amazing teacher. ...your explanation so well also awesome ❤🙏🙏

[koundilyakonwar]

Mam, pls use a more visible/bigger cursor while solving problems. It is hard to see what u point out with your present cursor. BTW love your videos.

[azharmohammed]

❤❤❤ No words to express ma'am... how much your lectures benificial for me!!🙏🙏🙏🙏☺☺❤❤❤

[kritika]

At 29:10 you have to write when r>>nR instead of writing R >>nr

[sujatarajure]

Mam, please make some short and special video on physics and chemistry all law's, theory for neet, jee.
A special video for each law. It will help to understand. Please, make a video exactly.
Definitely like those who agree.
Your videos are great to understand. I get the concept clear very quickly.your all video is awesome ☺️☺️🙂🙂🙂🙂

[MOKSH_NEHRA]

Oh actually I am doing that chapter or I really find out thank you mam for helping us God blessed you for us

[rajandevi]

Ma'am you are working very hard for us...Thank you soo much for caring about us soo much...may God bless you with much much happiness and success...hats off to you ma'am...for such an amazing determination for our education...you are bringing a revolutionary change in today's world...with all my respect Thank You for your blessings...❤
Respect++ 🙏🙏😇

[butramamatha]

Use mouse pointer differently, because we cant understand where the pointer is when u explain kirchoffs law..

[tarunaswini]

It's been so long. You helped in my 10 board exams. And those are the starting days of Examfear. U really motivate us to learn more and more. Thank you ma'am for helping me on my 10th board. And btw now am doing Btech 2nd year (IT). Thank you once again, ma'am.

[hargunshangari]

Ma'am...you make studies so easy and perfect...even my dad who has not studied much Phy and Chem finds it interesting and understanding it just by your videos...I'm waiting for chapter 4 of physics....Thnku ma'am❤❤

[martyr]

Ma'am plz it's a humble request plz complete these physics series as soon as possible Ma'am I understand every concept with you only plz Ma'am

[saniakhan_]

Concept definitely hua crystal clear!! :)
Ma'am, thank you so much for an amazing explanation..Ma'am, humble request to you please teach us the remaining chapters of physics, chemistry and biology of class 12th from the term 1

[truewords]

Thank you so much ma'am for your heavy efforts to improve our understanding of physics practically as well as theoretically.
