File:Power factor 0.7.svg

Original file (SVG file, nominally 669 × 559 pixels, file size: 25 KB)

Summary

Description
English: An illustration for power factor, showing the voltage, current, and instantaneous power waveforms along with the average power, over a full cycle, when the current lags voltage by 45°. The curve labels in the key are in descending order by peak value.

This graph was created using Gnuplot 4.2 and then edited with Inkscape. The gnuplot command used to generate the original graph was: 

plot \    cos(x) title "Voltage", \    0.8*cos(x-45) title "Current", \    0.8*cos(x)*cos(x-45) title "Power", \    0.2*sqrt(2) title "Average power"
