The instananeous voltages at three terminals marked X,Y and Z are given by v V_(Y)=V_(0)sin(omegat+(2pi)/(3))andV_(Z)=V_(0)sin(omegat+(4pi)/(3)). An ideal volmeter is configured to read rms value of the potential difference between its terminal. It is connected between points X and Y and then between Y and Z. The reading(s) of the voltmeter will be

Answer»

`V_(XY)^(rm)=V_(0)sqrt((3)/(2))`
`V_(XY)^(rm)=V_(0)sqrt((1)/(2))`
`V_(XY)^(rm)=V_(0)`
INDEPENDENT of the choice OG the two terminals
