In over compounded generator, full load terminal voltage is

Almost zero
Less than no load terminal voltage
More than no load terminal voltage
Equal to no-load terminal voltage

The correct answer is C. More than no load terminal voltage.

In an over compounded generator, the terminal voltage increases with increasing load. This is because the field current is increased with increasing load, which increases the magnetic field strength. The increased magnetic field strength produces a larger induced voltage in the armature windings, which increases the terminal voltage.

Option A is incorrect because the terminal voltage of an over compounded generator is not almost zero.

Option B is incorrect because the terminal voltage of an over compounded generator is more than no load terminal voltage.

Option D is incorrect because the terminal voltage of an over compounded generator is not equal to no-load terminal voltage.
