The voltage measured from one line to the common point with another coil winding is called the ____ voltage.

A) phase
B) delta
C) Start
D) connector

The voltage measured from one line to the common point with another coil winding is called the phase voltage. This is because it represents the voltage of the individual phase of the three-phase system, in contrast to the line voltage which measures the potential difference between two lines. The other options, delta and start, refer to different types of three-phase connections, while connector is not a relevant term in this context.
