Chapter 32: Q. 4 (page 905)

Draw the phasor for the emf $蔚 = (170) \cos ((2 蟺脳 60 h z) t)$ at $t = 60 m s$

Short Answer

Expert verified

Required figure is given below.

Step by step solution

Given information

We need to draw phasor diagram of given equation $蔚 = (170) \cos ((2 蟺脳 60 H z) t) a t t = 60 m s$

Explanation

We are given an expression for the instantaneous emf by

$鈭� = (170 V) \cos ((2 蟺脳 60 H z) t)$

We know that the general expression of instantaneous emf

$鈭� = {鈭�}_{鈭�} \cos (w t + 蠒)$

By comparing both equation

$胃 = (2 蟺脳 60 H z) t 胃 = (2 蟺脳 60 H z) (60 脳 10^{- 3} s) 胃 = 22.62 r a d 胃 = 216^{鈭�}$

Now, we can draw the phasor by rotating counterclockwise $216^{鈭�}$ from positive x-axis till the instantaneous emf becomes $- 137.5 V$ as shown below.
