I tried to solve this circuit problem using nodal analysis where 2Vx/6 - 10 - Vx4 = 0 and Vx/4 = ( 2Vx - VTh-)/5. I found Vx = 120Volts and VTh = 90Volts. Where is my mistake ?
here a better video on thevenin theorem with dependent sources rth in this video has been calculated using 3 methods ua-cam.com/video/D1QxFA9_U5w/v-deo.html
Sorry mam i am a follower of yours but here i want to share the image of calculation tell me how can i? And here i got your mistake when you put kcl at node between the resistor 3ohm and 5ohm. Here the equation should be ( I1=10+I) and you took it (i1=i-10) And Vth=(-390)volt
2 current sources present mesh analysis is only possible in outer mesh i.e, super mesh u have to grasp it or u can do nodal analysis but super mesh is fast
To find Rth, since we removed all the independent sources. So we apply this 1V voltage ,so that we can easily find current across terminals that gives Rth= 1V/ io
No no if rth is negative in thevenin curcuit take it is negative reason type nhi krna h muje other wise u will get wrong magnitude as well as direction

alhamdulillah..withy Allah"s help and after thinking hard I finally found my mistake.
Nicely explained !!
THANK YOU MAM.
Thank you so much ma'am ...nicely explain ❤️👍🏻
Mam,really it was very useful for me, thanks a lot, mam,,,from Bangladesh ❤❤❤
You writed and deleted how can I understand?
You can watch the moment by pausing the video.

Why we are taking additional sources of 1 volt/1A to determine Req in the case of such dependant sources??pls🙏🙏
We can take other voltages also like 2 or 3 or more but since calculations become easy with 1 volt, thats why we used it.
thank you ma'am. your videos are so helpful.
mam jo bhi topic bata kre to usko sikhane ki liye to btati h to ap normal level se batao
It helped a lot mam thanks
Thanks a lot
i am not sure if i understand the language or not
Thanks ma'am.
Thank you ma'am ❤️
Madam please change ur chalk piece
Thanks 👨
Mam यदि किसी dependent circuit me Rth ki value negative में आता है तो उसका answer negative में देगे या फिर positive me
Take Mod of Rth, -ve represents that I (test) is -ve.
i mean 2Vx/6 - 10 - vx/4 = 0
Nice video,
Thanks
Thank you mam
Very confusing... Explain clearly...
wowwwww thank you mam
Vth is -30 volt not 390🤫
Sorry mam i am a follower of yours but here i want to share the image of calculation tell me how can i?
And here i got your mistake when you put kcl at node between the resistor 3ohm and 5ohm. Here the equation should be
( I1=10+I) and you took it (i1=i-10)
And Vth=(-390)volt
At node Q i is out going current and i1 and 10 Amp are incoming current to node.At every node outgoing current is equal to incoming ie i=i1+10
yes i got the same equation as u got @sachin
Very nice mamm
Thanks! This example comes from a Bible book of Circuits 😀
Bible is shit ig. Its from Saduki
suit is nicely dressed
Tnx
nodal analysis should be the better way for this
Y u r using complicated method to find out Vth? Like outer loop,bla bla.. If u use a simple technik such as nodal,mess..that would b great...
ua-cam.com/video/3kF4zZaDGAM/v-deo.html .Hete KCl id used to solve it. It can be solved by both analysis depends on your choice & preference.
Hate* Here.Time taken is almost same.
2 current sources present mesh analysis is only possible in outer mesh i.e, super mesh u have to grasp it or u can do nodal analysis but super mesh is fast
Current 10A hai not 40A
Calculation is wrong
Tell me the right.
Point out where the Calculation is wrong as I am unable to find it.
The answers are correct, ma'm. I used a different method and obtained VTH = 390 V and RTH = 44 ohms.
@shoaib ahamadmir why ur not considered the 5ohms resistor???? In equation 1
noyce video
ap level thoda km kro ap to unko bta rahi h jinko malum nahi jinko pta h vo ku dekhege
4i-10 = 3i
-10=-i
I=10Amp
4i-40 is there check the equation 40 is looking like 10
Thank you mam.....29k views..but.. few..likes... This is not fair..🤔....
Mam Kitna bhi lgate hai answer hi nhi aata hai Mera bahut Dimag kharab ho jata hai
Solve 3-4 Previous years questions to find Vth & Rth, that will help you.
Why assume 1 volt while solving of Rth 🤔🤔
Give proper reason
Ya to ratta mara hai 🤣😆
To find Rth, since we removed all the independent sources. So we apply this 1V voltage ,so that we can easily find current across terminals that gives Rth= 1V/ io
@@rashmiagnihotritiwari8211 Ma'am it's not a proper reason plz give some reason that's why you use 1 volt not another value .
@@AK-so2vi find Rth we assume 1volt in voltage driver
Better find the short circuit current isc and devide it with vth without assuming anything
After removing independent sources, ckt needs any sort of reference source I e 1 volt or 1 amp source
Thanks
Thank you. You can ask for more topics on EC question paper.
Mam यदि किसी dependent circuit me Rth ki value negative में आता है तो उसका answer negative में देगे या फिर positive me
|Rth | lenge ...So it'll always be +ve
No no if rth is negative in thevenin curcuit take it is negative reason type nhi krna h muje other wise u will get wrong magnitude as well as direction
