You are working in an industrial plant. A bank of capacitors is to be used to correct the power factor of a 480-V, three-phase motor. The capacitor bank is connected in a wye. Each of the three capacitors is rated at 25 µF and 600 VDC. You have been told to reconnect these capacitors in delta. Can these capacitors be changed from wye to delta without harm to the capacitors?

Please help plot the voltage waveforms across the capacitor and resistor.
