Nov 09, 2011 · The flux produced by the shunt winding depends upon the current flowing through it. (i.e.,, is directly proportional to Ish & Ish= V/Rsh). When a variable resistance R is connected in series with the shunt field winding as shown in fig. (1), the shunt field current (Ish = V/(Rsh+R)) is reduced & hence the flux Ø. ................
