Answer:A
RMS value, E = Emax/√2 = √2πfrkpNΦ 7. The effect of short pitched coil on the generated EMF is _____________
A. increasing B. decreasing C. either increasing or decreasing D. none of the mentioned
Explanation: The effect of short pitched coil is to reduce the generated EMF and this reduction factor is cosε/2 and is referred to as coil pitch factor. 8. A winding is distributed in the slots along the air gap periphery
