My prof. had a question on his old exam that I was practicing on. However, I do not get the same answer and I am unsure on why. Can someone take a look and deduce where I have made an error in my math. THANKS!


And my work

 

What is the impedance Z of an inductance L at frequency ω?

 

LOL ... THANKS!! I feel very silly. Its really crazy that you can look at a circuit and not see simple mistakes.

 

It would help to remember that impedance increases as inductance L and frequency ω increase.
