Explanation:

No answer description available for this question.

 Siva said: (Feb 11, 2011) In 3ph power the phase angle b/w each ph in 120 deg elec.

 Jinesh said: (Jul 15, 2011) One rotation of the waveform is 360 deg. So to balance each phase are displaced at 120 deg.

 Gvk said: (Sep 15, 2011) In phasor representation of three phase supply the angle b/w each phase will be 120 deg.

 Vinay said: (Sep 20, 2011) 360/3 Degree phase is equal to 120 Degree.

 Karthikeyan said: (Oct 1, 2011) Total phase angle is 360 so each of 120.

 Murugesan said: (Dec 3, 2011) Phase difference in. 2 phase =90 degree, 4 phase=90 degree, 3 phase =120 degree.

 Happy Grewal said: (Dec 12, 2011) The phase diff is same in 3 phase system so the phase diff is 360/3 Degree phase is equal to 120 Degree.

 Nibha said: (Jan 11, 2012) Total=306 and for 3 phase angle the degree will be 360/3=120 degree.

 Ankita said: (Feb 5, 2012) One cycle constitutes about 360 degrees angle. So to complete a cycle in a 3 phase individual phases are 120 degree apart from each other.

 Sethupathi said: (Feb 6, 2012) In Three phase circuit angle between RYB phases are 120 degree.

 Jitendranath Panda said: (Jun 27, 2012) In 3phase system total phase angle 360'. So difference between two phase 360/3 = 120'.

 Vinod Kumar said: (Sep 21, 2012) In 3phase system Totle phase angle is 360. So each have 120 degree.

 Anil said: (Apr 5, 2013) Actually three phases are made 120 degree from per phases due to phase difference.

 Saishekar said: (May 23, 2013) Single phase 360/1 = 360. Two phase 360/2 = 180. 3 phase 360/3 = 120.

 Jose said: (Jun 17, 2013) Cycle = 360 degree and 120 degree by phases.

 Subhash Prajapat said: (Jul 6, 2013) Total 360. And for 3 phase angle the degree will be 360/3 = 120 degree.

 Chhabila said: (Jul 11, 2013) In a balanced system the three phase voltages or currents separated by a phase difference of 120 degree.

 Nithyashri said: (Aug 12, 2013) ANGLE B-R = 120. ANGLE R-Y = 120. ANGLE R-B = 120. TOTAL = 360.

 Naval said: (Jan 27, 2014) Three phase 360, So one phase 120.

 Ramadevi said: (Feb 5, 2014) Each phase having 120 degree. Answer is C.

 S.Hari said: (May 2, 2014) In alternator the three phase windings are set in 120 degrees displacement each other.

 Aaron S Mulwanda said: (Aug 10, 2014) The phase difference in 3 phase power system is the same. A complete circle has 360deg. Therefore, the voltages are separated by 120deg, 360/3=120.

 Hemanth said: (Sep 3, 2014) For the phase circuits other than 1 and 2. The phase angle can be calculated by using the formula "360/n". Where "n" is the number of the phases. In case of 2 - phase the angle is 90 degrees.

 Rajiv Gandhi said: (Nov 5, 2014) Each phase placed on 120 degree phase angle.

 Jagadish said: (Mar 14, 2015) In 3-phase s/m voltage are separate by 120.

 Naresh said: (Nov 13, 2015) Total 3 phase 360 for each phase 120.

 Dharmendra Kumar Singh said: (Jul 31, 2016) Total take complete in one rotation then formed 360 if division by 3 then come 120 so we take phase difference in three phase 120.

 Mukesh Kumar Ghotra Bemoth said: (Nov 7, 2016) In three phase system the phase sequence with angle 120°.

 G.Mounika said: (Nov 16, 2016) Nice answer with the clear explanation, Thank you all.

 Rupesh Raaz said: (Dec 18, 2016) In 3-phase balaced s/s, the 3-phase are 120' part from each other. Since, phase voltage are 120' appart to each other in a similarly mannar, the line voltage will be 120' appart to each other.

 Shankar Yadav said: (Mar 10, 2017) Total RYB angle is 360. 360/3 then each phase is 120.

 Siddu said: (Aug 29, 2017) Three phases are R Y B and they are differed by an angle of 120 degree.

 Shadan said: (Mar 13, 2018) 1phase =how many degree?

 Shyam said: (Jan 30, 2019) In three phase, each phase is displaced in 120°s; elec.

 Karan Chakravarthi said: (Oct 29, 2019) Why 2 phase system 90 degrees. Explain How?
