In this circuit i have got the following mesh equations :

mesh 1:

jI1+6jI2=12

mesh 2:

(j10+5-j4)I2+j4I1+2jI1=0

But in the book there is no j4 present. Why is that ?? I have tried with the -j4 term and the answer is not right. please help

Here is mesh 1:

(20+j10)I1-j5I2=60<30

mesh 2:

( j20+j10)I2-j5I1-j10I1=0

but here in mesh2 why is the term (-2*j5)I2 is missing in the book as i can see the current I2 is in series with them.

MEsh 1 is :

(20+j10)I1-10jI2+j5I2=0 [i have done]

(j10+j20-10j)I1+j5I2=0 [by book]

how comes the (-j5*2) comes as current I1 is not series with those inductors

MEsh 2 :

(j20+j10)I2-j10I1+j5I1-(2*j5)I2=1

but the book left the term (-2*j5)I2 but why ??

Those are some critical problems i m having. Please help me solving those problems.

Thanks
