Quick question please: At 18:20 why are you not doing 4/14 x 0,7778A? Confused on why you are using the 10ohm resistor with the current division rule?

@SkanCityAcademy_SirJohn

Жыл бұрын

In applying current division rule to two resistors, R1 and R2, i1 = R2/(R1+R2)*I and it switches for i2.

Great video sir...but on the second example..is it wrong if we consider the current I4' that's acting downwards to be negative and the one acting upwards I4'' to be positive?

Good example ..,just a quick question when we now considering 9A current supply do we include the 3ohms resistor since the voltage source is now short cct

@SkanCityAcademy_SirJohn

Жыл бұрын

Yes, the 3 ohms should be included. You just remove the voltage source and replace that with a short-circuit.

Also for example 1, where the current in 8 ohm is 4.5A, is it 4.5A because the current divides equally? Would the current always divide equally where it splits into two paths only?

Why is the current in example 2, where current source is replaced, why does the resistance of 7.87... ohm have the same current for the 5 ohm

@SkanCityAcademy_SirJohn

2 жыл бұрын

It is so because, the current divides at the node connecting the 4 and 10 ohms after flowing through the 7.8571, at the end the current combines and again and flow through the 5 ohms

sir in minute 15.53 i think it should rather (5//4)+10. As the current is coming from resistance 10, and that current is the one that's shared between resistance 4 and 5.

@SkanCityAcademy_SirJohn

Ай бұрын

No please, look at it this way. The 4 and 10 are parallel resistors since they are connected to the same two nodes. Instead of using the usual direction on the current source, take it the other way around.

In the first example why was the other current considered to be negative . Is there any trick to help me identify it.

@SkanCityAcademy_SirJohn

9 ай бұрын

There is no particular trick. The idea is since the currents I8' and I8'' flow in the 8 ohm in two different directions, you can choose to make either of them positive or negative. But normally for me, I make current in moving to the left negative and that moving to the right positive.

Why didn’t you use current divider rule when 9v acts alone to find current through the 8ohms resistor because the step you used was a little unclear to me

@SkanCityAcademy_SirJohn

Жыл бұрын

we could not do it straightaway because current division is applied to only two resistors at a time. So the best thing is to combine the resistors in the circuit first to obtain only two resistors before you divide the current among them.

What if the two resistors which the 9A is passing through have different resistance

@SkanCityAcademy_SirJohn

Жыл бұрын

If they have different resistors different current values will flow through them, so you need to us current division. The deal is, even when the two resistors are the same or not we still use current division rule. Just that when two resistance have same value, half of the total current is what flows through them.

is the current moving leftalways negative or an assumption

Please where from the 6/6+18 in the first example when using the current divider theorem

@SkanCityAcademy_SirJohn

Жыл бұрын

We want to find the current in 8ohms, but since 8 is in series with 10, the current in 8 will be the same as the current in 10. Since current division is applied to two resistors at a time we need to combine 8 and 10 in series which is 18, before we divide the current amongst 18 and 6.

Why didn't you use half of the current in the second question the same way you did in the first question when you got 4.5A

@SkanCityAcademy_SirJohn

Жыл бұрын

this is because in the first question, the two resistors sharing the 9A current were the same (10 ohms each), so current will be divided equally between them. But for q2, the two resistors have different values hence they cannot share the same current.... i hope you understand

Great explanation, however, I can't quite understand how you found the 1.5A, I got lost there

@SkanCityAcademy_SirJohn

Жыл бұрын

so you know, we had 6A approaching the node, and we want to find the current in the 8ohm, but the current that passes through the 8ohm is the same through the 10ohm because they are in series, so we add them, then we apply current division rule at the node. Hope you will understand this

You need to combine the two parallel resistors and add to the series resistor, that will be the total resistance. Then if you know the source voltage you can use voltage division to solve for the current in R1, meanwhile the approach also depends on the position of the resistor you are interested in

That has been clearly explained. Current approaching the node is 6A And we have (8+10) and 6 connected in parallel. Now to find current in 8 ohms, then it's basically 6/(18+6) * 6 which is 1.5A

Yes please. That is what I have explained in my first comment. That's the current division. We want to find the current in the 8 ohms. But 8 is in series with 10 which means same current will flow through them. So current in 8 Ohms is, 6/(18+6/ * 6A = 1.5 A

eveything is well understood...but why should we assume that the I8^1 in the 45V acting alone should be negative....shouldnt it be a standard something??why the assumption????

@SkanCityAcademy_SirJohn

I get you. But it's not about it being a standard. Once the two currents are pointing in opposite directions, then one is a negative current, I just wanted the final current value to be positive hence choosing the current with less value to be negative. It can also be the other way round. It doesn't matter, provided the final current value is the same, disregarding whether it's positive or nagative
