Inductors in ac Circuits - Physics help!?

A 4-mH inductor is connected to an ac voltage source of 151.0 V rms. If the rms circuit is .820 A, what is the frequency of the source?This is NON-Calculus based Physics! Please Help! Thx!

Answer:

I V/XL XL V/I 151/0.820 184Ω Now XL 2π*f*L f XL/(2π*L) 184/(2π*4x10^-3) 7330Hz
