Engineering Circuits: reactive,active, and power factor

AI Thread Summary
Total impedance was calculated at 14.23 ohms with an angle of 20.15 degrees, resulting in a power factor of 0.938. There was initial confusion regarding the impedance value, but it was confirmed to be correct. The discussion highlighted the assumption of a 120V supply with an angle of 0 degrees, which was necessary for further calculations. Participants emphasized that with the known voltage and impedance, the power delivered could be calculated. The conversation reflects a collaborative effort to resolve issues related to circuit analysis.

I found total impedance to be 14.23 ohms with an angle of 20.15. Found power factor to be .938
Pretty much stuck at a dead end trying part 2 and 3.

[STRIKE]Can you detail your calculation of impedance and power factor? 14.24 Ohms seems a bit small to me.[/STRIKE]
EDIT: Never mind, my mistake: you have the impedance correct.

What's the magnitude of the voltage supply, E?
 
Supply voltage or current was not given. Just found out we were supposed to assume a 120v with angle 0 supply.

Okay, so you known the voltage supplied and you know the impedance. You should be able to find the power delivered.
