[QUOTE="D.B0004, post: 5005463, member: 310553"] [h2]Homework Statement [/h2] An inductive load is connected to a 120V (rms), 60Hz AC source. The load draws 5.0 kW at a power factor of 0.81 (lagging). You need to improve your power factor to 0.96 (lagging) by adding a capacitor. What is the Capacitance needed (in uF)? [h2]Homework Equations[/h2] P/|S| = cos(phi) Q = V^2/X S = sqrt(P^2 + Q^2) [h2]The Attempt at a Solution[/h2] Please see photo with my solution attached. My professor says the answer is actually 398.17uF. I did this problem multiple times and never got that answer. I keep getting what I got in the photo attached (271uF). [/QUOTE]
