Voltage due to mutal inductance

  1. May 2, 2010 #1
    1. The problem statement, all variables and given/known data
    ok, i have one loop that has a current source (given as a phasor), a resistor R1, and an inductor L1. in the other loop there is an inductor L2 and resistor R2. something like this:

    src resistor dot + (V1) (V2)+
    *loop1* inductor M inductor resistor
    - - *loop2*

    V1 and V2 are across the respective inductors. dot is the dot notation. and M is the mutual inductance.

    2. Relevant equations

    3. The attempt at a solution

    my problem is that, with a similar problem expect with a voltage source, i can write kvl equations and solve for the current in each loop then solve for V1 and/or V2. however, i am stuck when it comes down to a current source. should i still do kvl equations?

    one more question, for the case of a voltage source, once i solve for current in each loop, is the voltage in (lets say) the second loop = jwL2I2 + jwMI1? where jwMI1 is the induced emf.
