The Sine Wave and Phase
In this chapter, the use of the sine function to determine instantaneous voltage and current values of a sine wave is discussed. The relationship between the period of a sinusoidal waveform and the electrical degrees of a cycle is described. The radian as a unit of angular measure is introduced. It is explained how to determine and specify the phase relationships of sinusoidal waveforms and the use of phasor notation is described.
At the end of this chapter you should be able to:
1. Determine the instantaneous value of a waveform at a specified angle using the equation ei= Epksin θ when given the amplitude of ...
