The e.m.f. induced in the armature of a shunt generator is 600 V. The armature resistance is 0.1 ohm. If the armature current is 200 A, the terminal voltage will be
A)640 V
B)620 V
C)600 V
D)580V

The terminal voltage can be calculated using the formula $V = E - I_aR_a$, where $V$ is the terminal voltage, $E$ is the induced EMF, $I_a$ is the armature current, and $R_a$ is the armature resistance. Substituting the given values, $V = 600V - (200A \times 0.1\Omega) = 600V - 20V = 580V$.
