Answer / pillay
1 KW means 1000watts
The calculating equation for power is different for an AC
circuit and DC circuit.
FOR DC it is voltage x amps. That is to find out the
currents
value divide the watts by the voltage.
For AC single phase circuit it is voltage (V)x current (I) x
power factor (PF).
FOR ac 3 phase circuit it is root 3 x V x I X PF
So for a single phase cct of 240 v a 1KW Power and assuming
a PF of 0.8 will take
1000 divided by 240 and divided by 0.8 will give you the
amps
