Ac Voltage

The instantaneous voltages at three terminals marked

X%20%2C%20Y

and

Z

are given by

V%20_%7B%20x%20%7D%3D%20V%20_%7B0%7D%20%5Csin%20%5Comega%20t

V%20_%7B%20y%20%7D%3D%20V%20_%7B0%7D%20%5Csin%20%5Cleft(%5Comega%20t%20%2B%5Cfrac%7B2%20%5Cpi%7D%7B3%7D%5Cright)

and

V%20_%7B%20z%20%7D%3D%20V%20_%7B0%7D%20%5Csin%20%5Cleft(%5Comega%20t%20%2B%5Cfrac%7B4%20%5Cpi%7D%7B3%7D%5Cright)

An ideal voltmeter is configured to read

rms

value of the potential difference between its terminals. It is connected between points

X

and

Y

and then between

Y

and

Z

. The reading(s) of the voltmeter will be
