A three-phase generator induces an alternating voltage with an RMS value of 220 V in each of its three coils. What voltage reading will the voltmeters display?

Explanation

Each coil in the three-phase generator produces an RMS voltage of 220 V. Therefore, the voltmeters connected to each coil will show a reading of 220 volts. Other options involving multiplication or division by √3 apply to line voltages or other configurations, which are not relevant here.
