Energy Stored In a Magnetic Coupled Circuit

  1. Aug 16, 2010 #1
    1. The problem statement, all variables and given/known data
    2j1tvki.jpg

    In this circuit i m given that Vs=12cos10t V Calculate the energy stored at t=15ms

    2. Relevant equations



    3. The attempt at a solution

    i have got I1 and I2 but i m confused how i can get the energy by using dot convention. Should i use -Mi1i2 or +Mi1i2 while calculating the stored energy ?

    I can see both the current enters ar dotted terminals thus i should use +ve sign before Mi1i2 but the book says the opposite. Why is that ?

    Thanks
