Example on DC Shunt Generator The magnetization curve of a shunt dc generator is shown below. The motor parameters are \( R_{A}=0.2 \Omega \) which includes the armature, interpoles and compensating windings resistances and \( R_{F}=30 \Omega \). A rheostat is inserted in the shunt field circuit and adjusted to give a no-load voltage of \( 170 \mathrm{~V} \). (i) What is the value of the rheostat setting? (ii) If the generator supplies an armature current of 103.5A, determine the armature terminal voltage. (Ans: \( 18.57 \) ohm, 145.3V]
