I need a little help here.

The question says to consider an inductor with L=16H and an internal resistance of 0.10 ohms. We wish to use this inductor to store 0.10 MJ of energy. What is the rate at which energy is lost to Joule heating in this system? It is not practical to store large amounts of energy in large inductors unless the wire is superconducting.

my work: I know the energy stored in an inductor is 1/2*LI^2. So how would I find the current given the information? And is the rate found by multiplying current by the emf?

Am I far off?
