20a - Norton's Theorem with Solved Examples #knust
In this video we are going to learn how to solve circuit problems using Norton's theorem.
Norton's theorem states that any linear circuit connected between two terminals can be replaced by a Norton's current IN in parallel with a Norton's resistance RN.
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 IN using KVL
3. Deactivate all independent sources, open circuit current sources and short circuit voltage sources and find the RN
4. Produce the Norton's equivalent circuit and reconnect the resistor you removed.
5. Find the current through the resistor using the formula I = RN/(RN + RL) * IN

04:30 - Solution to Q15 of Chap 2

Show me how to calculate current flowing in the network using norton’s theorem with two resistors in series and two in parallel and potential difference across the 2ohm resistor

Great video! I understand why 1//1 but how are they //2 as well shouldn’t it be (1//1)+2

@SkanCityAcademy_SirJohn Жыл бұрын

the combination of (1//1) and 2 are connected to the same two nodes, hence in parallel = (1//1)//2

Do u determine the direction of your nortorn current? Or it is your decision

@SkanCityAcademy_SirJohn Жыл бұрын

When it's theory, you are required to use the 'normal' Norton's method. So tell me your problem with finding In so I can help you

At 7:01 why is it leaving the negative terminal and not the positive terminal

When computing the IN, why are you using -5A for I2? was that a mistake? Thank you.

@SkanCityAcademy_SirJohn 7 ай бұрын

It's not a mistake, that's the right thing.

@Prossy796 7 ай бұрын

I mean clarify why you used - 5A for i2 as the rest were negative values. I need to understand. Thx.

@SkanCityAcademy_SirJohn 7 ай бұрын

@blesstouch5284 it's because this time the current i2 is leaving the negative terminal of 5v hence it's a negative current. Remember that conversationally, current that leaves the positive terminal is termed positive.

Your teaching is sooo nice SIr, but slight mistake, at 10:35, already u have taken -5, so u shouldn'y take -I2 also, becuase both minus signs cancel out each other and result will be positive, PLS GIVE ME CLARITY IN THIS SIR

@SkanCityAcademy_SirJohn Жыл бұрын

The negative has already been catered for in the current equation. That is why the equation in 10:35 had to be negative, negative to cancel out.

@respect_pro498 5 ай бұрын

incase the voltage source was place the right way we wanted it to be the current will still be positive so please check it out, im also confused please help me out@@SkanCityAcademy_SirJohn
