The following simple steps will lead you to resolve this query:
1) The resistance of the inductive coil is its inductive reactance which is given by the formula XL= 2πfL.
2) Substitute the values of f and L to get XL. You should get the answer as 7.85 Ω
3) Calculate peak current through the inductor using the formula I0= V/XL= 28 A
4) Now, finally calculate thermscurrent as Irms= I0/√2 = 19.8 A
