Answer: phase current is equal to the line current.
The star connection is denoted by Y. The star-connected system is also known as three phases four-wire system. It is the most favorable system for the distribution of AC power. AC circuits or Alternating Current Circuits are the circuits that are powered by Alternating Sources, either current or voltage. The source voltage and current in an AC circuit have a phase angle, which can be determined by dividing the resistance by the impedance.
Alternating Current (AC) vs Direct Current (DC)
The major difference between alternating current and direct current has been elaborated below.
Travels long distances with minimum energy loss.
Large amount of energy loss when travels long distance.
The frequency ranges between 50 hertz to 60 hertz.
The frequency is zero.
Rotating magnetism along the wire.
Steady magnetism along the wire.
Magnitude varies with time.
The power factor lies between 0 and 1.
The power factor is 1.
For a star-connected three-phase AC circuit, the _________.
Out of the given options, the answer is phase current is equal to the line current.
