What should be done for the altemator to take active power (load) on synchronous alternators? Devir sayısı artırılır A) The speed (rpm) should be increased Gerilimi arttırılır B) The voltage sould be increased Devir sayısı azaltılır The speed (rpm) shoul be reduced Frekansı azaltılır D) The frequency should be reduced Gerilimi azaltılır E) The voltage should be reduced

7. Conventional rotating exciter is basically a (a) d.c. shunt generator (c) d.c. series motor (b) d.c. series generator (d) d.c. shunt motor 8. With reduction of load on an alternator (a) The frequency increases (b) The frequency decreases (c) The frequency oscillates (d) The frequency remains constant 9. If the field of one of the alternators running in parallel is adjusted it will (a) Reduce its speed (b) Change its load (c) Change its power factor (d) Change its frequency. 10. If the field of one of the alternators running in parallel is adjusted it will (b) Change its load (a) Reduce its speed (c) Change its emf (d) Change its frequency.

Please solve , last time i got wrong answer

There are 175 slots in a 3-phase, 16-pole, 50 Hz., star connected alternator. There are 4 conductors in each slot and all the conductors in a phase are connected in series. Coil span is 130° electrical and the flux per pole is 0.04 Weber sinusoidallly distributed.    Calculate the emf induced per phase.
