Why do we need to assume there is a voltage source between points a and b in the the second example? In first glance I thought all the resistors are in series (5+10+5) because they have the same current

@SkanCityAcademy_SirJohn

Жыл бұрын

At glance, everyone will assume that the three resistors are in series but that's not true. You will need to think of plugging in a voltage source to see how current will be distributed in the circuit. Due to the presence of the node between 5 and 10, current will split. So no same current will flow throw all the three resistors

Be careful with the units. You tend to forget those. You can’t just say: V = 5I + etc. Because V is measured in volts, and I is measured in amps

Another great video sir...but why is it that in example 2, the 2A current is considered to keep circulating around 1 loop over and over

@SkanCityAcademy_SirJohn

Жыл бұрын

current produced by the 20v flows through both 10 and 5ohms and through the last 5ohms before it goes back to the source. meanwhile at the node where the 2nd 5 ohms is connected, current from 20v flows downwards while 2a flows upwards opposing eachother. now when you consider 2a to be circulating in that loop, it makes it easy to realize that it opposes the current produced by 20v in that branch

the 20v produces its own current I, and according to conservation of energy, the same current produced by 20v should be the same current that returns to 20v, hence 2A is considered to bee circulating in that loop passing through only the 5ohm resistor

well, good day, its very simple and easy to understand, consider the loop on the far left, the current in that loop will keep on circulating over and over. Now, the current produced by the 20v will flow throgh the 10, 5, and 5 ohms resistors. Since there is an open circuit, the current will not divide at the first loop where 10ohms, 5ohms and vth are connect, at the next node, the current wont divide but all will flow downwards in the 5ohm. notice that the two current values flowing in the 5ohms have opposite signs hence one should be negative. anyone of them can be negative, but the actual answer you get at the end proves the original direction of the current

I really appreciate this video too but please from the second example why is the current passing through the 5 ohms resistor ( I-2 ) A. I'm alittle confused, what if it's rather (2-I )A. That's not the answer though but just to clear my thought and to get a better understanding why the current in the 5 ohms resistor is ( I-2 ) A

@SkanCityAcademy_SirJohn

Жыл бұрын

So first, we assign current I which flows through 10 and 5 ohms on top because there is an open terminal at ab so no current flows through that branch. The current I flows through the other 5 ohms on the left. Notice that the current source at the far left points downwards which means it's going to circulate in the 5 ohms in the anti-clockwise direction opposing the initial direction of I

I don't really get your question, but the most important thing is, because of the open circuit, there will be no current in 3 ohms, so the current in 12 and 6 is same, which means 12+6 is 18 Hence I = 42/18 = 21/9

i don't understand how the 2A current only flows through the 5ohm resistor.

It depends on how you assign current in the entire circuit. I took the current produced by the 20v as my reference, which means that 2A will just be circulating in the immediate loop. Meanwhile whichever way you do it, provided it's the best approach, you need to get the same answers
