A 1 ton Air conditioner is appx 1400 watts . so
1400/230=7.8 Amp is the runing current.

In case of generator when we consume more power produces by it why load on generator increase and starts sound more. and how it is adjusted..

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.
