The instantaneous voltages at three terminals marked X, Y and Z are given by V_X = V₀ sin ωt,
V_Y = V₀ sin \(\left(\omega t+\frac{2 \pi}{3}\right)\) and V_Z = V₀ sin \(\left(\omega t+\frac{4 \pi}{3}\right)\)
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
