## Homework Statement

Find Z R=10Ω

Vs=120v

(PF)=0.72 Lagging

## Homework Equations

I=P/Vs(PF)

Z=Vs/I

## The Attempt at a Solution

I have I=P/Vs(PF) and transpose for I to get 4.34A

Then to find Z Z=Vs/I which gives 27.65ohm

When I put this back into (PF)=R/Z to confirm i dont get the right answer

Any help would be great
