| 9.3 Phasor (5) |
|
|
|
|
|
| Example 4 |
||||
| Transform the
following sinusoids to phasors: |
||||
| i = 6cos(50t –
40o) A |
||||
| v = –4sin(30t +
50o) V |
||||
|
|
|
|
|
| Solution: |
||||
| a. I A |
||||
| b. Since –sin(A) = cos(A+90o); |
||||
| v(t) = 4cos (30t+50o+90o)
= 4cos(30t+140o) V |
||||
| Transform to phasor => V V |
