19 - Solved Examples on Thevenin's Theorem #knust
In this video we are going to learn how to solve circuit problems using Thevenin's theorem.
Thevenin's theorem states that any linear circuit connected between two terminals can be replaced by a Thevenin's voltage Vth in series with a Thevenin's resistance Rth.
To find the current flowing in a resistor;
1. Remove the resistor you want to find the current through and mark the terminal
2. Find the Vth using KVL
3. Deactivate all independent sources, open circuit current sources and short circuit voltage sources and find the Rth
4. Produce the Thevenin's equivalent circuit and reconnect the resistor you removed.
5. Find the current through the resistor using the formula I = Vth/(Rth + Rl)

why we have no current in 2ohm resistor?

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 2 жыл бұрын

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

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 Жыл бұрын

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

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

@SkanCityAcademy_SirJohn 5 ай бұрын

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.

@viwemkhothi6349 Жыл бұрын

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

@SkanCityAcademy_SirJohn Жыл бұрын

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

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❤

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

@limnasainudeen4885 8 ай бұрын

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

No please

@ahallyahhaskins8140 10 ай бұрын

please explain why 😭

@SkanCityAcademy_SirJohn 10 ай бұрын

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