The trapezoidal MMF wave amplitude =3Ni/2. 10. MMF produced by one N-turn coil carrying a current i is ____________
A. rectangular of amplitude Ni/2
B. trapezoidal of amplitude Ni/2
C. rectangular of amplitude Ni
D. trapezoidal of amplitude Ni
Answer:A
The trapezoidal MMF wave amplitude =3Ni/2. 10. MMF produced by one N-turn coil carrying a current i is ____________
A. rectangular of amplitude Ni/2 B. trapezoidal of amplitude Ni/2 C. rectangular of amplitude Ni D. trapezoidal of amplitude Ni
Explanation: The MMF variation due to one N-turn coil is seen to be a rectangular wave of amplitude +1/2(Ni) or -1/2(Ni). advertisements
