Problem 1 Stator of 3-phase machine is excited by a current source as follows: I, lags Ia by 120 degrees and Ie lags I, by 120 degrees. Three-currents excite their respective windings on stator as shown in the figure. For Ia = -Im for 0 < 0 < 7 Ia Im for 7 < 0 < 27 (a) Draw Ia, Ib, Ic. (b) Find Bnet- (c) Explain significance of Bnet in terms of rotation speed and rotation direction.

A.a.Two electricians are discussing industrial cabling. Electrician A says that copper cable provides clearer transmission signals than fiber optic cable. Electrician B says that fiber optic cables will be larger thancopper cables with identical data transmission rates. Who is correct?B. Both Electrician A and Electrician B are correct.C. Only Electrician A is correct.D. Neither Electrician A nor Electrician B is correct.  A.b. Two electricians are discussing industrial cabling. Electrician A says that signal losses in fiber optic cableare more likely to be caused by splices and connectors than cable length. Electrician B says that wire-wrapterminations should be used when there isn't enough time available to use IDC terminations. Who iscorrect?A. Only Electrician A is correct.B. Both Electrician A and Electrician B are correct.C. Only Electrician B is correct.

please answer in hand written i dont understand where i can put the exponent..
