Current in Induction: Calculating Mutual Induction

[seanhbailey]

Homework Statement

Lets say that I have two inductors whihc share the same iron core and I run a current through the first inductor. I know how voltage changes under mutual induction, but how can I figure out the current produced through mutual induction?

 

[Astronuc]

How about conservation of energy, or power in = power out?

 

[seanhbailey]

So the current in the second inductor is the same as the current in the first inductor? Is there a way I can derive this?

The current in the second conductor depends on the number of windings in each conductor.

What does one know about transformers or coupled inductors? Faraday's Law?

yeah so that gives me voltage. I just divided by resistence right?
