Hi Im new to complex numbers and I can't figure out this problem.
(j20)(4 + j0.2)/
4 + j(20 + j0.2)
I'm not sure how how to go about doing this to get an answer of 3.77 + j0.944
Can any one help me?
on the tutorial it shows some of the working.
(j20)(4 + j0.2)/
4 + j(20 + j0.2)
= (j20)(4 + j0.2)/
4 + j20.2
= (j20)(4 + j0.2)(4-j20.2)/
(4 + j20.2)(4 -j20.2)
=(j20)(4 + j0.2)(4-j20.2)/
16 + 20.2^2
then not sure how to work the numerator out
this is 4 steps, the spacings hasnt worked unfortunately.
