    Question

    The emf induced in the armature of a shunt generator is 600V. The armature resistance is 0.1 ohm. If the armature current is 200A, the terminal voltage will be:

    A.

    620 V

    B.

    640 V

    C.

    600 V

    D.

    580 V

    Correct option is D

    Eg=600 V,Ra=0.1Ω,Ia=200 AEg = 600 \text{ V}, Ra = 0.1 \Omega, Ia = 200 \text{ A}

    Vt=EgIaRaV_t = E_g - I_a R_a

    Vt=600200(0.1)=580 VV_t = 600 - 200(0.1) = 580 \text{ V}​​​​
