I have been seriously struggling for my entire class understanding why these kinds of circuits behaved the way they do it and you just cleared it up so well. I was specifically curious about how a supermesh could possibly be accurate given you're essentially ignoring the middle elements, but the way you explained it made so much sense.

Informative class ✌🏻 but just one thing I noticed is that, we here learned to take Mesh Analysis by the others sign i.e. 20-3(i1-i3)-5i1=0(First mesh) and in that manner! Basically the same but we flip the signs, I guess It's different conventions in different regions!

I think ur right, because current direction is from the +ve terminal to the -ve terminal (which is the opposite to electron direction), But in the end, both are the same because we impose all this

solving for i_1 I got ... i_1=i_3-1 .... substitute i_3 - 1 for i_1 to get these equations (eq1) -3i_3 + 3 + 11i_2 - 2i_3 = 0 (eq2) 8i_3 - 8 - 5i_2 + 6i_3 = -20... simplify to get 2 unknowns... 11i_2 - 5i_3 = 0 (eq1) and -5i_2 + 14i_3 = 12 (eq2) using inverse matrix to solve... I got i2 = 0.47 A, i3 = 1.02 A, and i1 = 0.02 A.

So I had a question. When you solved the super mesh circuit, you drew a new composite box to sum the voltage drops around. Was there anything special about the new box you chose? Could you have not used one of the previous box's you'd drawn to sum the voltage drops around in order to solve for your currents?
@istainblack8 жыл бұрын
Ok so I can see now that calculating a voltage drop across smaller boxes you had previously drawn would not work as you would have to calculate a voltage drop over the ideal current provider, which wouldn't be so cool.

When you go from negative to postive of voltage it mean voltage rise it must be positive 20v in I1 (loop1)
@altuber99_athlete6 жыл бұрын
Ibnu Bastistah No. There are two ways to apply KVL (in resistive linear circuits). One is how you say, i.e. the voltage sign is determined by which terminal the current loop is *exiting* (and thus the voltage of the battery in that loop is positive and the voltage of the resistors is ALWAYS negative). The other way, which is the one he applis and the one I think Sadiku's book applies, is that the voltage sign is determined by which terminal the current loop is *entering* (and thus the voltage ofthe battery in that loop is negative andthe voltage of the resistors is ALWAYS positive). Now, is the equation obtained by the first methos the same or a equivalent of the one obtained by the secons method? Yes! Just multiply an equation by -1 and you'll get the other.
@iruettka5 жыл бұрын
shouldn't the current in loop 3 go in the opposite direction? since the current is going from - to + from the 40 V source?
@psychoturtle509 Жыл бұрын
You prob know this already, but for other commenter, to obey sign convention, each loop must go in same direction

4:30 so on passive elements (RLC) the passive sign convention is always positive with this method? and it's only the sources that you decide on positive or negative?
@UConnHKN6 ай бұрын
The sign convention is just that, a convention. The easiest thing to do is the write the positive and negative signs on the passive elements at the beginning of the problem and them as you traverse the KVL loop, use the sign for the element that you encounter first. ~Andrew F

@carsonprokopuik51016 жыл бұрын
KCL... sum of currents at a node is zero so if I1 is assumed as CW and I3 is also CW then I3 = I1 + 1A... which => 1A = I3-I1
