Question: What Is the formula for the amplitude of the fundamental curve?
Options
A : amplitude of the fundamental curve = 1.27 * flux density in the air gap * cosine (phase angle/2)
B : amplitude of the fundamental curve = 1.27 / flux density in the air gap * cosine (phase angle/2)
C : amplitude of the fundamental curve = 1.27 * flux density in the air gap / cosine (phase angle/2)
D : amplitude of the fundamental curve = 1/1.27 * flux density in the air gap * cosine (phase angle/2)
