5. 0/1 points Previous Answers SerPSE9 33.P009 My Notes Ask Your Teac An inductor has a 560-? reactance when connected to a 60.0-Hz source. The inductor is removed and then connected to a 51.0-Hz source that produces a 85.0-V rms voltage. What is the maximum current in the inductor? 246596 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. A Need Help?Read it

Explanation / Answer

XL = 2 pi f C

56 = 2 x pi x 60 x L

L = 0.1485 H

when f = 51 Hz  

XL = 2 x pi x 51 x 0.1485 = 47.6 Ohm

I_rms = V_rms / XL = 1.786 A

and I_max = sqrt(2) I_rms = 2.525 A
