How To Draw A Phasor Diagram

The total voltage v t of the two voltages can be found by firstly drawing a phasor diagram representing the two vectors and then constructing a parallelogram in which two of the sides are the voltages v 1 and v 2 as shown below. Take flux a reference. Concept of drawing phasor diagram for series and parallel r l c circuit is also very well explained.
