Question:

An inductor has a 59.6-Ω reactance when connected to a 60.0-Hz source?

An inductor has a 59.6-Ω reactance when connected to a 60.0-Hz source. The inductor is removed and then connected to a 46.0-Hz source that produces a 115-V rms voltage. What is the maximum current in the inductor?____ A

Answer:

XL(1) 2π fL 59.6 Ω L 59.6/2π 60 0.158 H XL(2) 2π*46.0*158 45.67 Ω XL(2) V/A A V/XL(2) 115/46.67 ? 2.25 A
