Homework Help: Is this the correct way to find apparent power and power factor

  1. May 18, 2013 #1
    1. The problem statement, all variables and given/known data

    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.

    2. Relevant equations

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

    3. The attempt at a solution

    S=60.8 VA

    Looks good. Maybe include:
    pf = 0.90 lagging

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