    I've been asked to identify this circuit, give the relationship between Vin and Vout/Vsense, and give the three currents. The gate drive voltage is a square wave, and I have no details for Vin. Can someone please help?

    Your circuit is missing some labels - ground is the lower end of the resistor, and Vout is the right side of the coil.

    Assume Vin is a DC source of appropriate voltage and current. What would Vsense be measuring?

    The key things to consider are the two steady state conditions (when the gate drive is stable high or low) and the two transitions (gate drive going from low to high, and from high to low).
