17.5 ROTATING PHASOR AND SINUSOIDAL WAVE
We cannot imagine our world without electric power. In electrical engineering, first thing is to learn generation of sine wave. A rotating vector known as phasor is responsible for it. A phasor rotates at a given angular speed. Its component on y-axis decides the magnitude of sine wave. This fact is described in Figure 17.2.
Let us base our first graphical program on this phenomenon.
Problem: Write a program to show a “Rotating Phasor” and generated sine wave.
Solution: In electrical engineering, it is assumed that a phasor (vector) is rotating at constant angular speed. Its component on y-axis decides the magnitude of the waveform at that instance. Therefore, one rotation of vector results in one cycle ...
