RL Circuit - Problem finding Unknown Inductor

[Brad1983]

Here is the circuit:

I need to find:
I
Z
VL - Voltage on Inductor
XL
L

I have I and Z but I can not figure out VL, XL, and L. This is what I have for I and Z:
-----------------------------------------------
a.)
I= V_R / R = 170 V / 34 kΩ = 5 mA
b.)
Z = V_s/I = 200 V / 5 mA = 40 kΩ
------------------------------------------------

I know XL = 2 x pi x f x L

This is where I am stuck.

Your Z in b.) is the magnitude of the impedance (impedance is a complex quantity). So write:

$$|Z| = \sqrt{R^2 + (\omega L)^2}$$

Does that help?

not sure because we do not use OMEGA.

ω = 2πf

 

[Brad1983]

ω = 2πf

oh I did not know that. We do use 2*pi*f. Thanks gneill
