sinusoid to and from the time |

| domain to the
phasor domain: |

| • | Amplitude
and phase difference are two principal |
||||||
| concerns in the
study of voltage and current sinusoids. |
|||||||
| • | Phasor will be
defined from the cosine
function in all our |
||||||
| proceeding
study. If a voltage or current expression is in |
|||||||
| the form of a
sine, it will be changed to a cosine by |
|||||||
| subtracting
from the phase. |
