Free and printable phasor diagrams have been collected for you i high definition and quality. For engineering students who are learning about phasor diagrams, can stop by and save all these diagrams in this post. A phasor diagram gives the snap shot at a particular moment, means its give the idea of different quantity how its change with respect to stationary reference without knowing the actual magnitude. It is also used to show the phase relationships between two or more sine waves having the same frequency.
The main value of phasor diagrams is that they can be used, not only to represent waveform diagrams, but also in carrying out calculations involving ac waves. The calculations can involve any of the common values (RMS, peak values, phase angles etc.) and will be much quicker and easier than performing the calculations on waveform diagrams. Every phasor in the diagram will have the same angular velocity because they represent sine waves of identical frequency. The length of the each phasor arm is directly related to the amplitude of the wave it represents, and the angle between the phasors is the same as the angle of phase difference between the sine waves.
You can see the details in the diagrams as posted above. Phasors can be used to calculate unknown values in different types of circuits where capacitors, resistors and inductors may be connected in series or in parallel to achieve different effects, provided some basic rules are followed.
