Question { Genpact, 100277 }

Why the generator rating in kva

Answer

the kva is apparent power here E and I are taken into
account but kw is real or true power here an addition power
factor is taken so VA=E*I
KW=E*I*power factor

Question { Power Grid, 13726 }

What is the difference between "Earthing" and "Neutral"?

Answer

the earth and neutral are closly related because the
earthing is a electric wire connected to ground to make low
impedance path to avoid hazardous voltage flow through the
circuit(metal parts of electric equipments).in case of
neutral line when we check the wiring circuits and electric
posts neutral lines are also earthed .

Question { BEML, 8769 }

how can we check a fully charged battery?

Answer

its so simple because the voltage is always mentioned in the
battery we can check it using a multimeter or voltmeter or
using a hydrometer we can check the specific gravity of the
battery a fully charged battery have a gravity of 12.75 and
weak have 12.50 and below

Question { 6635 }

why transformer calling in VA rating

Answer

copper loss depends on current andiron loss depends upon
voltage.hence the total loss in a transformer depends upon
volt-ampere(va) so rating of transformer is given in VA
