Which statement is true regarding the phase current in a delta connection?

In a delta connection, the phase current is characterized by its relationship with the line current, which is crucial for understanding how the three-phase system operates. In such a configuration, the phase current is indeed less than the line current. This is due to the way the currents are distributed across the delta-connected loads.

Specifically, in a delta connection, each load is connected across two lines. As a result, the line current is greater than the phase current because the line current is the sum of the currents flowing through the two phases connected to that line. Therefore, the phase current, which flows through each individual load, is lower than the current that is flowing in the lines that supply the entire delta network.

Understanding this relationship is vital when calculating currents in electrical systems, particularly in three-phase systems. Recognizing that the phase current is a fraction of the line current helps in designing circuits and analyzing load conditions in practical applications.
