where:

primary generated e.m.f. per circuit:

primary load current per circuit:

Jl = abli = abe (0,1 — ja2);
primary exciting current per circuit:

.

thus, total primary current:

/o = I1 + /oo = e (ci — jc2) ;
where :

and the primary terminal voltage:

#0 = Ūl + hZ,
= e (di - jdz)
where :

^ = — + T-Q^ -f. ^Oc2 and d2 = roC2

or the absolute value is :

substituting this value of e in the preceding equations, gives,
as function of the primary impressed e.m.f., e^:
