oh missed that. SO final answer should be (28.93 - 22.27j)/240j = -0.093 +0.120i which equals to 0.152 < -127.59 in phasor form. Thanks a lot gneil, and sorry for that coin in my last solution sheet :D
Anyway I was concerned bcuz when we find the magnitude of Va in polar form it's greater than the magnitude of the parallel voltage in polar form. However; I decided to check the total voltage of Vz2 + Va in rectangular form and it was equal to the parallel voltage which I guess my answer is...
You're right Z3 here is wrong, but when I calculated the total Z I used the right calculation which is 64 + 48i , and the answer of the Z of Parallel would still be 66 - 42.74. And thus the total Z is 82 - 64.07. And when we calculate Va we just need the Z parallel and Z tot so the mistake in...
Here you go, this is my work. BTW I tried also to find the current through the capacitor and then find the voltage but I got a different result as well :S
There is this one weird thing that I came across when solving the question, as you know to find the voltage of node A, you have to find the voltage of the capacitor, therefore; firsr you need to find the voltage of the whole parallel part by applying voltage divider rule like this (Zparallel/...
Okay. The thing I'm supposed to do it using delta to wye, however; If I ever have time, I'll try the node analysis. And if you don't mind, can I solve the whole thing, and attach it so I can show and you could tell me what are my mistake, if I have any?
And thanks a lot for your help;.
Okay that's great, I think I got the picture. I'll solve the whole thing and I'll scan and attach it to show it to you so I can know your remarks, of course if you don't mind?
Okay. I got your idea, by that Va should the voltage across the capacitor and Vb should the voltage across R3 but the thing how could I find the voltage or apply the voltage divider rule in case of a sinosoidal voltage source.
just to tell you
Z1= 16 - 21.33i
Z2= 51.2 + 38.4i
Z3 = 64 - 48i...
Hello, I have this question that I've been working on. The question requires me to find the current across an inductor in a Delta circuit, so I want to solve this question using Delta-to-Wye method. so I transformed it using the method and I found the total impedance of the whole circuit, then I...
Hello,
I have a difficulty calculating the energy of an electron orbiting a nucleus, let's say we have a a hydrogen atom, there is only one electron orbiting around the proton. And since the radius never changes.
r = 5.29 x 10^-11 m
charge (qp) of proton= 1.60 x 10^-19 Coulumbs
charge (qe)...
