Look , Always try to understand what quantities you have
and their significance. This will help you derive other
quantities yourself using the first principles. Lets derive
KWhr from current I !

Firstly you need to know the voltage at which this current
is drawn from its supply. V

Once you have this info you can find the power flow = V x I
this is in W if you use SI units throughout

Divide it by 1000 to get KW

KWh = unit of energy therfore its Power x time

Now how long would your current be drawn for. say its a fan
drawing 2 Amps and you keep it on for 5 hrs at 240V

(240V x 2A x 5hr)/1000 = 2.4 KWhr

Answer / virendra joshi

KWH = watt x no of hour /1000

W = v x I for single phase
w = 1.73 x VL x IL x Cos@

Answer / s.arul

ohms law: V = IR
you know the current rating, you take the machine
resistense using megger. calculate the voltage rating of
machine.
1 phase: power = V * I * power factor (watts)
3 phase: power = 1.732 * V * I * power factor (watts)
ENERGY (KWH) = POWER * TIME
so, we can calculate the KWH or MWH of the machine....

why a single phase motor of same rating takes more amps than the three phase motor? as single phase motor at 230v takes 5amp per HP while 3 p motor takes 2.5amp per hp at 230v.
