The Phasor diagram explains the relation between voltage and current. This comparison happened in the Sinusoidal functions and solved using the Sinusoidal expression.
phasor diagram is nothing but the vectorial representation of time-varying periodic signals(most common are sine and cosine) , whose magnitude is given by the amplitude of the signal and the direction (angle..) is given by the phase difference. this makes life a lot easier , calculations in vector-algebra domain is more easier when compared to trigonometric domain because here we can resolve any 'n' no. of vectors and by performing simple algebra of addition and subtraction gives us the desired result. Whereas in trigonometric domain we need to expansions like sin(A+B),cos(A-B) etc etc which is a laborious task
The voltage phasor diagram is important in analyzing electrical circuits because it helps visualize the relationship between voltage magnitudes and phases in different parts of the circuit. This diagram allows engineers to understand how voltages interact and how they affect the overall behavior of the circuit, making it easier to analyze and troubleshoot complex electrical systems.
The real part of a phasor in electrical engineering represents the amplitude or strength of the signal. It is important because it determines the magnitude of the electrical quantity being measured or analyzed, such as voltage or current. Understanding the real part helps engineers analyze and design electrical systems more effectively.
'Angular displacement' is the angle by which the secondary line-to-line voltage lags the primary line-to-line voltage. It can be directly measured by constructing a phasor-diagram for the primary and secondary line-voltages for a three-phase transformer.
Impedance may refer to: the ratio of the voltage phasor to the electric current phasor, as in Electrical impedance, a measure of opposition to time-varying electric current in an electric circuit. Characteristic impedance, a measure of opposition to electric current propagation in a transmission line. Impedance matching and Impedance mismatch. Vacuum impedance, a universal constant. Electromagnetic impedance, a constant related to electromagnetic wave propagation in a medium. Mechanical impedance, a measure of opposition to motion of a structure subjected to a force. Acoustic impedance, a constant related to the propagation of sound waves in an acoustic medium. Linear response function, a general way to represent the input-output characteristics of a system.

I already have the graph drawn on graph paper with 2 waves on , my phase shift is 1.5 and 180degrees. Anyone know how to add and subtract the sinusoidal ac waveforms on the graph, and by phasor diagram?
Theoretically, it can be drawn at any angle. Normally, however. it is drawn along the real, positive, axis (i.e. facing East). For series circuits, the reference phasor is the current and, for parallel circuits, the reference phasor is the voltage. For transformers, it is the flux.
Number of turnsAnswerI assume that you have a phasor diagram of a transformer, and wish to identify the primary phasors and the secondary phasors?For a three-phase transformer, this is fairly straightforward, provided the usual procedure for drawing a phasor diagram has been followed. Whenever you start to draw anysort of phasor diagram, you usually start by selecting a phasor of reference and draw that in the horizontal positive direction. For a three-phase transformer, the phasor of reference is usually the primary phase voltage A (or however else it is identified: R, red, or whatever). The remainder of the primary phase voltages are then drawn, enabling the primary line voltages to be constructed (which, in the case of a primary delta are the same as the primary phase voltages!). So if you can identify the phasor of reference, then you have identified the primary-winding phasor diagram. As the primary and secondary voltages are not usually drawn to scale, relative to each other, you can't assume a turns ratio from the phasor diagram. The labelling might also help, as high-voltage phase and line voltages are identified by upper-case letters, while low-voltage phase and line voltages are identified using lower-case letters -but, remember, these identify high- and low-voltages, not which is primary and which is secondary (primary winding is connected to supply/secondary winding is connected to load).For single-phase transformer, the phasor of reference is the flux set up in the magnetic circuit, and voltages/current phasors are drawn relative to this. In this case, the primary line and induced voltages are usually identified as V1 and E1, and the secondary induced voltage as E2 (sometimes, the Es and Vs are interchanged). Again, the lengths of the primary and secondary voltages are not necessarily to scale relative to each other.
By calculate do you mean calculate the connections required or phasor diagrams? full question would be helpful

Most definitely not, as resistance, reactance, and impedance are not themselves phasor quantities. However, it is derived from a phasor diagram (by dividing a voltage phasor diagram by the reference phasor, current).
Phasor Zap happened in 1978.
