Homework Statement
I have to find the normal frequencies of a coupled LC circuit. However, this LC circuit is coupled by an inductor, not a capacitor.
__|C|________|C|__
|...|...|
^I(1)...|...^I(2)
|...|...|
{L}...{L'}...{L}
|...|...|
|...|...|
--------------------
I'm sorry, I didn't have a picture but that's basically the circuit.
Homework Equations
I1+I2=0
I=dq/dt
These equations are for an LC circuit coupled by a capacitor:
L(d2q1/dt2)+(1/C)q1+(1/C')(q1+q2)=0
L(d2q2/dt2)+(1/C)q2+(1/C')(q1+q2)=0
The Attempt at a Solution
The only attempt I could figure out that it would be similar to that of a circuit coupled by a capacitor. I don't know if I'm on the right track or not and if I am I'm not sure how to modify the two equations.
