### Phasors and Phasor Algebra - Electronics Hub

Jul 03, 2015 · Assume that an AC circuit has two voltage waveforms like 20 volts and 30 volts, say V1 and V2 respectively. If the voltage wave V1 leads V2 by 60 0 phase. Lets find the total voltage of the AC circuit by phasor addition or vector addition method. First we should draw the phasor vector diagram with the two voltage vectors, a parallelogram. Phasors, Phase Shift and Phasor Algebra Basic The dashed-line phasor is the same angle as the solid-line phasor reaching from point B to point A, just moved so that its tail rests at the circles center in order to plot its vertical projection on the rectangular graph to the right of the circle. As you can see, the new phasor $$V_{AB}$$ is 180$$^{o}$$ shifted from the old phasor $$V_{BA}$$.

A single-phase load is supplied by a single-phase voltage source. If the current flowing from the load to the source is 10 150°A and if the voltage at the load terminals is 100 60°V , then the A. load absorbs real power and delivers reactive power. Power Triangle and Power Factor in AC CircuitsWhere reactive power (Q) is in volt-amperes reactive, voltage (V) is in rms volts and current (I) is in rms amperes. Then reactive power represents the product of volts and amperes that are 90 o out-of-phase with each other, but in general, there can be any phase angle, between the voltage and the current.
