What is the meaning of area of cross section of wire?

If you cut directly and squarely across the width of a wire then you will look at the end and it looks like a circle. The area of that end is the cross sectionarea, which is Pi x r^2. A larger cross section area results in lower resistance per foot when the type ofwire is the same.

What is armature and field?

The field of a synchronous generator is the winding to which the DC excitation current is applied. The armature is the winding to which the load is connected. In small generators, the field windings are often on the stator, and the armature windings are on the rotor.
