Difference between Star and Delta Configuration?

Question

Accepted Answer

Star configuration connects all three phases to a common point, while Delta configuration forms a closed loop with each phase connected to the next.

Star configuration is more common in low voltage applications, while Delta configuration is more common in high voltage applications.
Star configuration provides a neutral connection, while Delta configuration does not.
In Star configuration, the line voltage is equal to the phase voltage, while in Delta configuration, the line voltage is square root of 3 times the phase voltage.
