Finding apparent power and power factor from real and reactive power

[pokie_panda]

Homework Statement

A load operates at a voltage of Vx = 125V-rms and absorbs P = 55W andQ = 26VAR of power. Use this information to calculate the apparent power (S) and the power factor (pf) for the load.

Homework Equations

S = sqrt [ P^2 + Q^2]
pf = P / S

The Attempt at a Solution

S=60.8 VA
pf=.90

Looks good. Maybe include:
pf = 0.90 lagging

since your load is inductive (it absorbs positive reactive power).
