Hi All,
My attempt is a little different, could any of you guys confirm I've gone about this one the right way?
Using KCL at V-
I=(0-Vx)/Rf
Vx=-I*Rf
Using KCL at Vx
((Vx-Vout)/R1)+(Vx/R2)=0
(R2*Vx)-(R2*Vout)+(R1*Vx)=0
Vout=(R1+R2/R2)Vx
Vout=-(R1+R2/R2)I*Rf
Vout=-kI
k=(R1+R2/R2)Rf...
In the case of a d.c. generator, if V=E–IaRa when current flows through the armature, why does V = E at no load?
Why does the resistance element become disregarded at no load? Is this because the resistance can't cause the voltage to drop at no load?
Hi Guys,
I've pretty much got my head around everything up to finding the current for the Thevenin model... -v1 + (j4 x i) + (j6 x i) + v2 = 0 ... -415 + (j4 * I) + (j6 * I) + 415 = 0
but I'm really struggling with how to approach the complex math to achieve i = 41.5 + j41.5
I'm not...
Hi,
I am trying to find the current of a circuit using mesh analysis so far I have;
My voltages
V1 = 415 ∠ 90° or 0 + j415
V2 = 415 ∠ 0° or 415 + j0
impedances
Z1 = j4
Z2 = j6
My formula is;
-V1+Z1*I+Z2*I+V2=0
Which equates to;
-0+j415+j4*I+j6*I+415+j0=0
Could...
