Problem P. 4398. (December 2011)

P. 4398. An inductor with a self-inductance of 36 mH and an unknown one to be wound opposite are connected in series. The coefficient of coupling between the coils is given, k
= M/\sqrt{L_1L_2}=0.75. Find the self-inductance of the unknown coil to have a mmaximum current in the circuit.
