Today we will be solving a circuit with a transformer in it.
00:06
Um, now, looking at the circuit, we realize that we want to redraw this into something that we can solve.
00:13
So what that's gonna look like is get reading of the transformer.
00:22
We have our power supply r resistor r capacitor.
00:28
And then we will get rid of the transformer here, um, and then looking at this section of the circuit, we can see that we won't be able to solve this unless we do what's called the delta y transformation.
00:47
And so that basically takes your resistors from this configuration to this configuration.
01:00
And you can see how that will help us solve this circuit.
01:03
So continuing with redrawing our circuit, we will draw these resistors in the white configuration on a capacitor and our conductor mhm.
01:36
So we know that the values of our capacity and in dr aren't going to change here.
01:42
Um and this is actually positive for since it's an induct, er ah, now we can complete our circuit with our final resistor and labeling i not that we are asked to calculate.
02:03
Okay, so let's go ahead and put in some values we know that this isn't going to change here, um, to calculate the values for for our a r b and r.
02:22
C.
02:24
Um, we will do that using the delta y transformation.
02:28
So our is gonna be 12 times 18/36 just six or b is 18 times six or 36.
02:49
So that's gonna be three on our c is 12 times six or 36.
03:03
Just a tip.
03:12
Okay, so now we turn to now, we need to label thes components here.
03:21
So to do that, we need to know what our turn ratio is and is going to be in two of her n one just equal to one half.
03:33
So then our voltage is gonna be one half 36 at zero phase delay.
03:47
And this is positive here because of the dot convention that were shown up here...
