The question is asking about the current and voltage of a 3-phase motor connected in star configuration.
In a 3-phase motor connected in star configuration, the line voltage is equal to the phase voltage.
The current in each phase of a star-connected motor is equal to the line current divided by the square root of 3.
For example, if the line current is 10A, the phase current in a star-connected motor would be approximatel
