Hi everyone here, hope you enjoying this summer ..
i'm taking ' elements of electromagnetic ' course this summer session and i just have a little question here
[Broken]
in the yellow shaded statement
shouldn't it be dl = (l/N) dz instead of dl=(N/l) dz ?
By the way, it's not a...
i have a problem in PSPICE
i created a simple circuit but after clicking on ' simulate ' , a message appears :

any help ? thanks
the question is to find the magnitude and phase angle of the resistor voltage in the circuit below :

i want you guy's to check my solution please .
thanks .
=> Vn = 29/30 v and Vo = 14.5 v
=> I s = ( Vn - 0 ) / 15k = 64.44 uA
I a = ( Va - Vp ) / 1k = -466.67 uA
I b = (Vb - Vp ) / 2k = 766.67 uA
I c = ( Vc - Vp ) / 1.5k = 22.2 uA
I g = ( Vp - 0 ) / 3k = 322.2 uA
ok ^^
Here is my solution :

i am confused with this problem , part b :

my question is : Does Vsat reffer to the right amp or the whole circuit ? or something wrong with this problem ? thanks :)
As we know , the average value of a function over is :
i wanted to calculate the average value of a function over its entire domain ( e.g )
firstly, i divided the interval into 2 intervals &
and calculated the F_avg for each ,,, is my way correct ? thanks !
Thanks all of you for your help , i appreciate that !
BTW i got the same answer here :

thanks again :)
i came across an example in my textbook as shown :
http://img593.imageshack.us/img593/8444/img1314i.jpg [Broken]
if we used KCL and In = 0 :
In = I_100 + I_25
=> I_25 = -I_100
but as being written in the answer , I_25 = I_100 !
could anyone explain it for me ? thanks
Hi all ,
is it possible to use the source transformation for dependent source ..?
i guess yes because i came across a problem which asks to use source transformation to find Vx as shown :
