A 3-phase machine has integral slot winding with fundamental distribution factor kd1, the distribution factor for nth harmonic kdn is ____________

A 3-phase machine has integral slot winding with fundamental distribution factor kd1, the distribution factor for nth harmonic kdn is ____________ Correct Answer less than kd1

kdn=(sinqnγ/2)/(qsinnγ/2) and examples will show that kdn is less than kd1. This has the effect of reducing the nth harmonic EMF in comparision with fundamental EMF. This is certainly an advantage of distributing the winding in slots.

Five theatres PVR, DT, Chanakya, Regal and Maratha Mandir screen two out of ten films based on Romance, Thriller, Horror, Adventure, Children, Drama, Documentary, History, Religion and Cartoon. Each theatre exhibits only two films and allots two different slots for them, wherein slot I is before slot II. Chanakya screens a Horror film in the first slot, while Maratha Mandir exhibits a Historical film in the second slot. DT exhibits a thriller film in the second slot and Regal exhibits a documentary film. Drama must be exhibited only in the second slot. The children’s film and the Cartoon film are exhibited in the same theatre while the religious film is not in the first slot. If Chanakya screens a Religious film in its second slot, then which of the films can be screened by theatre Regal?
