In a DC circuit Power (P) in watts is equal to Voltage (E) times Current (I).
1000 Watt = 1 kW
P = EI thus I= P/E
For kW then I = (P x 1000)/E
Example with Power of 2 kW and Voltage of 250 V DC:
I = (2000/250) = 8 Amp

How many amps will a 120 kw dc motor require?
Depends on the voltage.
How do you calculate load in KW?
You have to know 2 things in order to perform the calculation. You will need to know the power (KW) and either the amps or the voltage. If you know voltage you can determine amps and if you know amps you can determine voltage. However with solely the KW you do not have enough information to calculate either. Here is the formula: 1 Phase: KW = (E x I x pf)/ 1000 3 Phase: KW = (1.732 x E x I x pf)/1000 Where E is voltage, I is current, and pf is Power Factor
How do you calculate kw in three phase generator?
Use the following equation, kW = Amps x Volts x 1.73 x pf/1000.
Calculate 75amps and 440volt what is the value in kW?
The formula you are looking for is W = I x E. Watts = Amps x Volts divided by 1000.
What would full load amps be on a 480volt 90 kw electric heater be pulling 36 amps per leg?
90 kW on 480 volts single phase would be 187.5 amps. On 480 v 3-phase it would be 108 amps.
How many amps will a 120 kw dc motor require?
Depends on the voltage.
How do you calculate the dc circuit breaker rating for a given kw?
the given kw Divide by the your voltage
Can direct current kW be converted to KVA?
With a dc system the kW are always equal to the kV times the amps. It's only with ac that the kW are usually less than the kVA by a factor called the power factor.

How many KW in 32amps?
There are zero kW in 32 amps. Watts are the product of amps times volts. Once you find the voltage of the system multiply it times 32 amps and then divide that answer by 1000. This will give you the answer in kW.
How to convert from kV into kW?
Multiply by Amps.
Calculate 75amps and 440volt what is the value in kW?
The formula you are looking for is W = I x E. Watts = Amps x Volts divided by 1000.
How many amps is 8.5kw at 240volts?
The equation you are looking for is Amps = Watts/Volts. To change kW to watts, multiply kW x 1000.
How do you calculate the ac amps when you have the DC volts DC amps and the ac volts?
the answer is dc volts are rectified from ac volts and the amperage will be the same unless you account for the slight drop from the rectifier. dc volts from a battery have no relationship to ac volts. you can derive ac volts from a dc source using an inverter.
What is the calculated amperage for an electric range rated at 16 kw?
16 kW at 240 volts runs at 16000/240 amps, or 67 amps.
How can you convert kw to amps?
watts = volts x amps kilowatt = 1000 watts
