Shunt field coil more number of turns with smaller cross section
Series field coil Less number of turns with larger cross section

Answer / issacsamuel

A shunt generator is a type of direct current electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current. A direct current (DC) generator, not using a permanent magnet, requires a DC field current for exitation.
A field coil is an electro magnet used to generate a magnetic field in an electro-magnetic machine, typically a rotating electrical machine such as a motor or generator. It consists of a coil of wire through which a current flows.
