1. The problem statement, all variables, and given/known data
I have a single loop RL circuit with no source. I am given the the inductance of 3mH, as well as that energy storage is as follows 1 J @ t=0 and 100mJ @ t=1ms. No current is given. I have to find R. I don't need the answer just some ideas of where to start. Thanks!
The only equations I can think of are p=i(0)^2 * Re-2R/L t , 1/2Li(0)^2, and i=i(0)e-R/L t.
I initially got .0015 Ohms (which I know is incorrect)
