Hi,
Question: if I have a standart three-phase system (127 V) with 1 resistor on each phase, and there is no neutral wire. Also the resistors are different in resistance. Then why the phase voltage is going to change? Because the voltage that is provided by generator on one phase is constant = 127 V?
I'm just starting electrical engineering and it really blows my mind, so please help

thanks

 

It is constant if it is measured between the generators neutral and each phase. Since the generator neutral is not connected on the load neutral, then any imbalance in the load resistance causes this voltage difference. It is just AC circuit analysis.
