Oh its okay I understand, you have to include the entire thing and not just the individual sections.
ie.
xi (1) = 40/2 = 20
xi (2) = 300/2 + 40 = 190
xi (3) = 20/2 + 300 + 40 = 350
Ive been given this table in a lecture (attached) and I'm not sure what they're using to fill in the columns of Xi an Yi, it looks like it should just be half of each section in Yi, but that is not the case in Xi, can anyone please explain this to me.
Thanks =)
and to get the current through R2 and Xc2:
Itotal * (R2/(-jxc2+R2) = 1.956 < 49.97° * (1000 /-j1693+1000)
then to get IXc swapped the value for R2 on the denominator for Xc
got the following answers:
IR2 = 0.999 <109.4°
IXc2 = 1.68 < 19.4°
Forgot to mention that the AC voltage input value on the diagram is wrong, its actually 4.75 < 0° sorry!
first found Z with:
Ztotal = (R2*Xc2)/(√(R2^2+Xc2^2) + R1 + Xc1
Where
R2 = 1000
Xc2 = -j 1693
R1 = 820
Xc2 = -j 1421
break it down to polar form to get
861 < 30.57° +...
I've been asked to prove KVL and KCL using this circuit, but my vectors don't add up.
ei Vr1+ Vr2 + Vc1+Vc2 ≠ Vtotal, same goes for Current, but I at least got the correct angle for the current
Tried using vector addition, using addition of the vectors in complex form and even tried using this...
I've been given the following problem (attached), not sure how to tackle this one, do I use mesh/node analysis and super node analysis, or can I find the v in the loop with the dependant voltage source then use that as the supply to the second and third loops?
Not sure, any help would be...
Ive been given an assignment with the question being question 13of the following pdf:

here is a screenshot from one of my lectures talking about how to find active power (P) and reactive power (Q)
He calculates P using 100*10 Cos (30-(-30), which I understand, though the answer he gets is 200W, but whenever I calculate it I get 500 because cos60 = 0.5 and 0.5*1000 is 500...
I have the equation E(t)=7*sin(11000t+∏/3) and I measured the following:
E(.22ms) = .422V
Frequency = 1.751kHz
Period = 572.0 μs
Peak = 7V
Peak-Peak = 14V
E(rms) = 4.8V
E(average) = 105mV
I've calculated the following to compare
E(.22ms) = .422V
Frequecy = 1.75 kHz
Period...
Hi there,
in this youtube tutorial about AC circuits
http://www.youtube.com/watch?v=JiLdrAHBBRc&feature=plcp
at about 4:08 It's supposed to be z=√(R^2+(XL-Xc)^2)) but in the example she does Xc-XL, is there a reason for this or is it a mistake in her working??
