8. An alternator requires an excitation of 2A to produce on short circuit its full load current of 60A. The same excitation on open circuit gives an emf of 260V. If the resistance of the armature is 0.82 and the terminal voltage on full load is 11000V, find the induced emf when the pf is a) unity (Ans. 684V) b) 0.6 leading (Ans. 533V)
