Given vg $=369$ cos$(50,000$t$)$ V$.$

The coefficient of coupling k is adjusted until the peak amplitude of i$1$ is maximum.

$$a$)$ What is the value of k$?[$Hint: Use reflected impedance which includes k and determine when Zin is minimum which yields the max current$]$

$$k $=$ Answer $1$ Question $4$

b$)$ What is the peak amplitude of i$1?$

$|$ i$1|=$ Answer $2$ Question $4$ A
