When calculating the speed of a rotor required for a particular frequency of synchronous generator we use the equation 60f/p Is this p is the number of pole pairs of rotor & do we consider the number of pole pairs in the stator is 1?
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.
