## Homework Statement

The coupoing coefficient of K' of a linear transformer is adjusted so that

**Z**ab is purely reissitive when ω= 25k rad/s. What is

**Z**ab?

## Homework Equations

Not sure

## The Attempt at a Solution

I'm not sure how to being this problem. For one, from what I've been reading I'm not sure how the connection between frequency and

**Z**ab is made. Also, I'm not sure what the question is asking for by 'purely resistive'. Does this mean there is no comblex part?

I'm pretty sure I understand the coupling coefficient. I'm not sure how to apply it to this problem.
