Intersection of Rf line and magnetization curve will give ____________

1.	Intersection of Rf line and magnetization curve will give _____________(a) No load terminal voltage(b) Field current at no load(c) Both a and b(d) Not specific dataThe question was posed to me in class test.The above asked question is from Characteristics of Self Excited Generator topic in section DC Generator of DC Machines
Answer» Correct option is (c) Both a and b The BEST explanation: When OCC is plotted against terminal voltage and field current where, field RESISTANCE line is also drawn, an INTERSECTION point will arise when OCC almost becomes constant DUE to saturation effect. So, corresponding value field current and no-load voltage can be observed from x and y AXIS resp.
