The main advantage of using fractional pitch winding is to refuce

due to fractional pitch EMF can be approximately made into sine wave
losses due to harmonics reduced
saving in conductor material
mechanical strength of coil is increased.

What happens to the contents of RAM (Random Access Memory) when the power of the computer is turned off?

Permittivity is expressed in terms of

A device connected to the computer which converts digital signals to analog and vice-versa is

A 3 phase, 6 pole induction motor operates on 440 V, 50 Hz, supply. If the actual speed of the motor is 960 rpm the slip will be

Ns = 120f/P
Slip=(Ns-Nr)/Ns
Ns = 1000 and Nr = 960
from equation of slip, S = (1000-960)/1000
S = 0.04 or 4%
