Question 109Electricity/Electronics - QMED70% to pass
In a three-phase circuit, how far apart are the phase voltages?
AI Explanation
The correct answer is A) 120° apart.
In a three-phase circuit, the phase voltages are spaced 120 degrees apart. This is a fundamental principle of three-phase electrical systems, where the three phase voltages are displaced from each other by 120 electrical degrees. This 120-degree phase difference is what allows three-phase systems to provide a more balanced and efficient power distribution compared to single-phase systems.
The other options are incorrect because: B) 160° is not the correct phase difference, C) 180° would be for a single-phase system, and D) 360° would represent a full circle, which does not accurately describe the phase relationship in a three-phase circuit.
