According to the DELTA CURRENT LAW, how do you calculate line/coil current?

The DELTA CURRENT LAW relates the phase current in a three-phase delta-connected system to the line current. In such systems, the relationship is defined by multiplying the phase current by the square root of 3, which is approximately 1.73. This occurs because in a delta configuration, each phase is connected directly to the line, and the total line current is influenced by the combined effects of the phase currents.

By calculating the line current as phase current multiplied by 1.73, you account for the way currents interact in a delta configuration. This results in the line current being higher than each individual phase current due to the phase relationships and the way they contribute to the overall line current. Understanding this fundamental relationship is crucial for anyone working with three-phase electrical systems, as it affects calculations for current ratings, load management, and safety considerations in electrical systems.

Taking this into account, it becomes clear that the other options do not reflect the correct arithmetic relationships specified in the DELTA CURRENT LAW, hence solidifying the correctness of the chosen answer.
