Current Drawn

[linguist]

I am trying to calculate the current drawn by an inductive circuit from the total Power, Voltage & Power Factor.

If I have a an inductive circuit with a load of 10kW as an example & the circuit has a power factor of 0.4, the voltage is 100v 50Hz.

I know from Ohms law that you have I = P/V so 10,000/100 =100A

But the power factor is 0.4 making the circuit draw more current so how do I factor this in?.

Cheers

I'm not sure if this is correct, could you have a look & see for me please.

Power in an AC circuit is Volts X Amps X Power Factor.

Power is Constant at 10kW in this case so 100V X 250A X .4pf = 10,000W--10kW.

Do I have this correct?

Hello,

Since
P=E*I*pf

then
I=P/(E*pf)

Thank you MrAl,

You have cleared that up for me perfectly once again.

Cheers
