Exitation voltage is the voltage required to establish the
working flux in the air gap.It is DC in nature and applied
across the field winding which is generally placed on the
rotor in the case of alternator.

With the application of exitation voltage, current strats
flowing through short circuited rotor windings,this current
is termed as exitation current.

Alternator works on the principle of magnetic locking
between stator and rotor fields.The exitation provide the
neccessary rotor field,without which alternator would not
convert mechanical energy into electrical energy.

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
