Hello to all..
I'm facing difficulty in part a)

I'm not able to determine the current in circuit A to be able to put it in the below formula so to determine the crosstalk voltage in circiut B



Below are the diagram and the question.
Please guide me to find out the current since I don't have the value of the inductance in OHM

 

I assumed since L1 compared to the sum of R1 and RL1 is very small so it can be negligted .then current =1/100=.01 A

If I'm wrong please advice me

 

How can you compare an inductance to the sum of resistances? That's like saying that a person's height is small compared to their income.
