    Find the value of the inductance L shown in the attached diagram.
    My Answer:
    V=L*d(i)/d(t)
    L=V/d(i)/d(t)
    V=25cos250t
    I=14sin250tmA
    d(i)=14cos250t
    L1=(25cos250t)/(14cos250t)=25/14=1.7857
    Lt=2L+2L+L^2/2L=
    2L+2L+1/2L=4.5L
    Lt=1.765*(2L+2L+L+L)=
    1.765*6L=10.71
    L=10.71/4.5=2.38
    Final answer: 2.38
