Required figure is given below.

Step by step solution

Given information

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

Explanation

We are given an expression for the instantaneous emf by

$\in = (170 V) \cos ((2 π \times 60 H z) t)$

We know that the general expression of instantaneous emf

$\in = \in_{\circ} \cos (w t + ϕ)$

By comparing both equation

$θ = (2 π \times 60 H z) t θ = (2 π \times 60 H z) (60 \times 10^{- 3} s) θ = 22.62 r a d θ = 216^{\circ}$

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