I've been having a hard time with my school project and wondered if you could help me.

My task is that I have to modell a circuit of wireless charging (seen on the picture).

For help I was given this Wikipedia link and later on I was told by my teacher that my main goal should be writing and solving the differential equations that determine this circuit and thus be able to say how much current flows through

*Rl*for given

*Vs*.

So far I've read countless of topics regarding this project (Including this site's part for AC current.), but the thing is, I'm still struggling with the mathematical aspect of it.

And for this I'm reaching out to you guys, with hope that some could help me out on this one.

Thank you in advance!

ps: I only need guidance not solving the whole thing for me (before anyone accuses).
