[@studylife1476]

You are a life saver, I wish you success and never ending happniess. I finally got this god forsaken concept.

[@SkanCityAcademy_SirJohn]

thanks so much for your comment

I watched a lot of videos but nobody teaches like you, you are a hero

[@SkanCityAcademy_SirJohn]

Aww thanks so much

[@panashepanaxe629]

You're too much. Though it's tough,you make it simple 👏.Keep on helping us to understand better

[@SkanCityAcademy_SirJohn]

You are most welcome. Thanks for watching and commenting as well. Hope you are going to share this great news with your friends and class mates....

[@josephwasheni648]

Good lesson

[@AlexMchachi]

why we have no current in 2ohm resistor?

[@mohammedibrahim4826]

Love u from the deeepest part of my heart thank u bro tommorow is my exam❤

[@jeremiahcornell4185]

at 0:20, what dow the D lnthat you write in blue mean? I assume it meant solution or something like that. S ln ?

[@SkanCityAcademy_SirJohn]

It's solution

[@limnasainudeen4885]

@8:21 , current through Rload is just vth/Rth right. Since resistors are in series, current will be same

[@SkanCityAcademy_SirJohn]

I don't get your point please

[@limnasainudeen4885]

My bad..you are correct

[@sambillafranklin8156]

When calculating for the thevenin's voltage how do you determine wheather to move in the clockwise direction or anti-clockwise direction

[@SkanCityAcademy_SirJohn]

That is determined by yourself. Vth is the open circuit voltage between the two terminals ab. So with a being + and b being - ,depending on the circuit you take your direction. But then if you do it the right way, whether clockwise or anti-clockwise your answer should be the same, it may just differ by sign.

[@azizfakhr6738]

Thank you 😍

[@SkanCityAcademy_SirJohn]

You are most welcome

[@manofphysics9142]

I am abit confused. In qn3, why did the other 2 ohm resistor not have current flowing through it?

[@TheoRantshabo-x9r]

Its in an open circuit Both currents from 7V and 10V don’t pass by it

[@JuliusJuuko-i5p]

Y is not 3 considered will moving in first loop while finding Vth, thank you

[@princeasramah5382]

Please with the second question finding the Rth why is the equivalence of the two resistors in parallel in series with the ten ohm resistor

[@SkanCityAcademy_SirJohn]

We assume that there should be a voltage source at Rth, we have two 5 ohm resistors on the left and one 10 ohm on the right. Once current divides at the branch , the combination of the two 5ohm resistors are in parallel with the 10 ohm In the right

[@ayushianand2169]

How u apply kvl in middle row How how take current in different resistance

[@Sams_XR]

Thanks alot

[@SkanCityAcademy_SirJohn]

You're welcome

[@shahabasov7627]

first of all thank you a lot for help.I'm still confused why we took 2 parallel 3 and 2 parallel to 2(6.23) .Before examples circuit part with the same appearance has been taken as series .

[@SkanCityAcademy_SirJohn]

I get you, you should understand that resistors are in parallel if they are both connected to the same two nodes, 2 and 3 on the left are connected to the same two nodes, same applies to 2 and 2 on the right. If they are connected only end to end then they are in series. Take notice

[@viwemkhothi6349]

why is the no current I1 in the 2 ohm (middle loop for Vth)

[@SkanCityAcademy_SirJohn]

Because the current produced by 7v will move along the loop and from the +ve terminal to the -ve terminal in that circular manner, same as for 10v so literally no current will flow in that 2ohms resistor. At the end the law of conversation of energy must be fulfilled

[@AmNotAugust]

thank you

[@SkanCityAcademy_SirJohn]

You are most welcome

[@ErnestinaDompreh-c9d]

Hi, thank you very much for explaining so simply I worked but all the time 😢i struggle to get the right direction of current flow😢, that is identifying how current will flow in the current will flow in the circuit before finding vth. That very crucial cus the moment i get " i "wrong, vth is also wrong 😢pls can you help on that❤

[@SkanCityAcademy_SirJohn]

Yes I can. Have you joined my telegram group??

[@oracle0422]

for Que 3 I got vth as -9.2v Can it be possible?

[@SkanCityAcademy_SirJohn]

No please it's not possible. Consider trying again

[@Discoverypluse]

Give me answer which question is showing in thumbnail

[@ahallyahhaskins8140]

I thought that the current produced by the 10v would flow into the other 2ohms resistor

[@SkanCityAcademy_SirJohn]

No please

[@ahallyahhaskins8140]

please explain why 😭

[@SkanCityAcademy_SirJohn]

It's because of the open circuit at the top there. So the current will just be revolving in the immediate loop

[@amounikorea6066]

​@@SkanCityAcademy_SirJohn I can't understand why all the resistors are connected in parallel and also in calculating 3 with 6 ohm the result is (3+6)/(3*6) no ???
