1. The problem statement, all variables and given/known data

2. Relevant equations

No relevant equations
3. The attempt at a solution
Trying to figure out what type of circuit this is. As far as i can tell its just a circuit with voltage, inductors, and resistance and a switch
Only thing is i dont know what type of circuit this would be called.

One way to classify circuits with reactive elements (inductors, capacitors) is to distinguish them by the number of independent reactive elements. By independent I mean that they can't be combined and reduced to single reactive elements of the same type (by combining parallel or series connected inductors, or parallel or series connected capacitors). Then you can call the circuit a "first order", "second order",etc., circuit.

The above circuit would be a second order circuit. You can expect a second order differential equation to arise if you need to solve analytically for the transient response.
