T and Pie Equivalent Linear Transformers

[@Grind_or_Die]

Bro I rarely ever comment but ur vids are coming in clutch for second year ece

[@hibahasan9627]

Explained in a very simple way. Thank you loaaaads

[@bimalkhataniar2389]

Very good information sir...

[@hieuvuong444]

can you explain for pi network with coupled coeficient k =1

[@deepanshumahour3318]

but these equivalents are not for general cases like it's only applicable when the turn ratio(Ns/Np) of the transformer is 1.

[@bimalkhataniar2389]

This case is only for linear transformer

16:17 12-9 is equal to 3 rather than 4 sir :)

I think there's an error here. The equivalent T circuit choice depends only if the dots are on the same side, not if current is flowing into the dots on both sides. If the dots are both on the same side, you use the first T circuit. If the dots are on different sides you use the other T equivalent circuit. This is regardless of whichever way current is flowing.

I don't think that your statement is accurate. To write any equations using mutual inductance, you need to know where the polarity dot is on both inductors and you need to know the direction the reference currents are flowing. More specifically, if reference current i1 is flowing into the dot of inductor L1, then L2 gets a positive voltage polarity on it's dotted terminal. Similarly, it reference current i2 is flowing into the dotted terminal of L2, then L1 gets a positive voltage polarity on its dotted terminal. To be clear, I am still learning about these equivalents myself. However, I can not see how the equivalents can depend only on where the dots are alone without any connection to what the reference currents are doing. The dots are totally arbitrary by themselves in any given circuit and you need to know what the induced voltage polarity is to be able to analyze the circuit mathematically. It seems to follow that you also need to consider the reference current directions as well.

Very nice!

sir what is that red thing? whitener or eraser
