why in three phase 440 circuit in all phase current is
almost equal L1-35 A,L2-34 A ,L3-31 A but in nutral when i
check with clamp meter it shows 25 A?

Can any body tell gulf interview question for experienced electrical engineer ?
True or false question. 1.The fuse provide phase and neutral 2.power loss in electrical circuit can take place in (resistance or inductance or capacitance). 3.two phase system each phase has separated by a phase difference of (90 or 180 or 270 or 45). 4.3 phase balanced star connected load neutral current shall be (line current or phase current or zero or unity)
