Tq bro
1:43:00 Emf= terminal voltage when no current flows so IR=0, or when internal resistance is 0(ideal source)
Mam please dont stop doing this sessions... Thank You mam 🔥
Sss exactly🥳
@@shobikakumartq mam
ma'am at 29:57 you have put electron value as 1.9 * 10^-19 but it is 1.6*10^-19 right
1.Drift velocity and relaxation time will be max at T1
2. Terminal voltage =EMF when there is no current flow
3.mam I1 value - 0.122A
💪🤘good start dear 💕
@@shobikakumar ❤
2:18:19 the polarity of 3 v must be opposite so the answer for that question will be emf equivalent is 3v resistance equivalent is 2 ohm
Because we have assumed the -ve side to be higher so only we have used -4v so polarity should be opposite
Mam how to check the loop direction whether it is clockwise or anticlockwise ..??
Theivame nandri❤
1:42:56 When there is no current flow then emf=V
Mam, current will always be opposite to the direction of electrons, but you mention as same direction at the beginning of the session topic
the direction of flow of electrons (Actual current - to + charge) is opposite to the direction of flow of conventional current.(+ to - charge)
2:33:33 Mam current 1 is 0.13 A pls check!
1:19:22 option b
Decrease in relaxation time
1:24:50 drift velocity and relaxation time increases with respect to temperature and resistance
Mam resistance increase pannumbodhu area vum constant thana mam
Appo R=¶l/A irukum bodhu
When length increased 2times resistance increases 2times thana mam.
No da when the conductor is getting stretched the area won't be same it will change because radius will change like we study in Poisson ratio
@@shobikakumar but in Google it's given as resistance gets doubled...and area is same....
No search properly in google typing what happens to area if the length is stretched?
Because conductor can be stretched in all dimensions as you already know. Here we are discussing only one dimension which is length in this case area will be constant. There are other cases where area will change and other parameter will be constant
@@ranjithganesan5886 perfect explanation 🤘😎
@@ranjithganesan5886 clear bro..🤘
Terminal voltage = EMF it can be done when , I=0
8:00 when conductors was given current the electrons will be aligned uniformly and flow of current takes place
9:48 electrical energy
+ve higher potential
Emf=terminal voltage
= When there is no current in the battery.
Sprb mam👍👍👍🙏🙏👏👏👏🤟🤟🤟
Mam pls derive derivation part also 😢 it is useful for our board exam also mam
1:43:00 when no current is drawn from the cell
Ma'am e- hp to lp pohum nuh soneenga but ana onga diagram lah lp to hp pohuthe.. elam senthu kolambuthu🥺.. help pls
2:10:46 the total ans is wrong search in Google for correct answer
Kirchhoff's rule la neenga apply KVL sollala mam..
Super eh teaching pandringa mam❤😊
vd1>vd2 and for relaxation time t1>t2
Thank you for keeping my heart smile and my i shine mam
Awesome Class mam 🔥
mam would u plz derive si unit for mobility...
Where could I get those formula sheets?
Please take derivations from book also
When circuit is open v=€

Mam NEETla 120 in physics layum chemistry layum mark yedukkurathukku subject sollunga please
When there is no current . Emf and terminal voltage is same
maam in 2:16:21 how minus i have cheked again and agin it should be + right
Thanks mam 😍😍
How was you chemistry
@@pragadeesu3796 very easy mine was set 3 . You??
@@meena87594 iam set 1
How much will you score
@@pragadeesu3796 I think set 1 was tough right? Mine was kinda easy . My teacher told set 1 ,2 mark questions were tough. I think might be more that 90 percent mark
@@meena87594 yeah little bit tough, but I will pass in it .
Open circuit terminal voltage=emf
Vd and tough decrease aavum.. with respect to increase in resistance and temperature
2:13:33 once again explain
upload for computer science also
i will train you i am good at cs🙂
@@rishincr7505 how?
@@sabthagiri3389 yeah that make sense how will teach you. are u in ig
@@rishincr7505 no
@@rishincr7505 are u a teacher?
Current move opposite to electron
Super section
Mam ray and wave optics
Thank you so much mam.....❤

Mam super🔥🔥🔥🔥🔥🔥🔥🔥
Mam 12standard computer science
Mam please applod state board potion
Mam I have one doubt shall i concentrate on first vol or 2 nd volume mam in school they re saying to study vol 2 mam pls give me suggestions
its ur wish
Vol 2
Has majority
But vol 1 need to study
For to get good marks
You study both
Thank u guys
@@SRM_EDITZ_2006 entha school bro nee?
Mam I had watched your electromagnetic induction lecture it was awesome
Please continue this for other lessons too
Adad ✨💥🔥🔥
shimon sir edunga itha class edhum purila
Mam Please Update All the Chapter within this month mam
1:35:57
Yoo 🔥🔥
I am 10th std I I wach tjis lecturs so I can sleep well😅😅 and it is usefull I can learn something
Mam you are taking class awesome mam
there is no playlist mam
Mam this lecture is enough for neet
Hi maam
Is this applicable for karnataka also?
*Electricity
thankyou mam
If current const Vt=E
What is charge
Ok
Wave optics mam
super session mam
Please can anyone send me the PDF of current electricity
