is emf is indued if dc is passed through coil
what sort of general awareness questions are asked in o.n.g.c entrance exam?????????????????
Why fuel tanks to be earthed ?

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)
what is different between IP55,IP54 and IP66?
2 Answers ABB, Global Industries,
main difference between ac and dc?
what are the reasons of CT circuit faulty in busbar protection scheme?
armature is that part in which current is induced since in dc motor we supply current to the conductor so why we call it armature?
Why we use CT on differant phases of 2ph.PT detection for brush-less static excitation of 3ph.,400v Synchronous Generator? What happen if use CT on same one of VT phase?
