Chapter 32: Q. 3 (page 923)

A 110Hzsource of emf has a peak voltage of 50V. Draw the emf phasor at t=3.0ms.

Short Answer

Expert verified

Required emf phasor is:


Step by step solution

01

Given information

We are given that Peak voltage = 50V,frequency = 110Hz,t=3x10-3s

02

Explanation

We know that 蝇=2蟺f

蝇=2蟺脳110Hz蝇=220蟺rad/s

then, We need to find angle胃

胃=蝇t=220蟺脳3脳10-3=0.66蟺胃=23蟺x57.29掳(1rad=57.29鈭�)胃鈮�120鈭�
