hello
I got another one here im not sure about
I have a circuit
values
v1 = 20 + j0
R1 = 15 + j0
L1 = 0 + j10
C1 = 0 - j5
first I added R1 and L1, R1 + L1 = (15+j0) + (0+j10) = 15+j10 = Req
then I found C1 in parallel with this Req, like this
(0-j5) (15-j10)
(15+j10)(15-J10)
so,
15 x 15 = 225
15 x -j10 = -j150
j10 x 15 = +j150
j10 x -j10 = -j^2 100, if -j^2 is equal to -1 it would leave -1 x -100 leaving 100
so that leaves 225 -j150 +j150 +100
-j150 +j150 cancel leaving 225 + 100 = 325 ohms
as far as I know that's it. it says "a)" which leads me to believe that there is a "b)" but its not on there
so, any help or confirmation would be great. I don't know how to confirm this using multisim
thanks
simon
