The cosine angel between voltage & current known as power
factor.
P.f play important role in electrical system. If the p.f
decreased,the equipment take more current from source, it is
harmful to devices. If the p.f increased to about unity, we
can get more real power. This is used in power plant.But
NLDC CORRECTION P.F Another way p.f is chosen a suitable
value that is helpful to consumers and suppliers.
