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

Answer / saju

Full load current =kw*1.78 so, 1.78A will take for 1kw

i am going to give the JSEB,RANCHI exam for power plant,so i need some samples of papers related to that,so please send me these papers by my mail id.
