How do you compute ampere if the given is kvA kW power factor and voltage?
Some confusion hereKW and KVA are units of power. The ampere is a unit of current. If you divide power by the voltage involved, you can determine the current involved, in amps. Power (watts) = volts x ampsA volt-amp is a watt. (A volt times an amp is a watt.)I=(KVA*1000)/(1.732*V) (Three Phase)AMP=KW/1000*V*PF--------------------------------------------------------------------------------------------------------------KW or KVA can be converted to one another but you cannot convert them to amps. You can compute amps by using this formula,KW = I x V x 1.732 x P.F/1000 (Three phase)KVA = I x V x 1.732/1000 (Three phase)
How do you convert 5kW to amps if your voltage is 120?
P, the power in kW (kilowatts) is related to V (the supply voltage) and I (the current in amps) by the Power Law: P = V x I So, to get the current: I = P / V If you have something that uses 5 kW (which is the same as 5000 watts) and the source voltage is 120 V, then the current drawn in amps = 5000 / 120 = 41.67 amps.
How do you calculate KW from Volts?
Kw can be calculated from volts be using the formula p=(voltage)square/resistance*1000
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 many amps will a 120 kw dc motor require?
Depends on the voltage.
How can i calculate kw of 125 ampere?
Depends on the voltage. If you multiply the voltage with the amperes you get watts. If it's a 400V group you have 3 times 230V 125A
Which is greater 1kw equals equals KVA?
In the case of DC, and in AC when current and voltage are in phase, a volt-ampere is the same as a watt (and therefore, a kilo-volt-ampere is the same as a kW). In the case of AC, when current and voltage are NOT in phase, power = voltage x current x power factor; the power factor is the cosine of the angle between current and voltage, and it is always less than or equal to one. In such a case, a kVA would be less than a kW.
How many kilowatts equals to one ampere?
To answer this question a voltage and pf (power factor) must be stated. kW = I x E x pf/1000.
What is the kilowatt output of an electric heater that has an ampere draw of 50 A and a voltage source of?
At 240 v and 50 amps the power is 12 kW because 240x50 is 12,000.
How Kilowatt to amperes?
The symbol for 'kilowatt' is 'kW', not 'Kw'.The kilowatt is used to measure power, whereas the ampere is used to measure current. These are different quantities, so you cannot simply convert one to the other. It's a little like asking "How do you convert kilometres per hour into newtons per metre?"!However, if you know that the power-rating of a kettle is 3 kW, and the supply voltage is 230 V, then you can find out the resulting current by dividing the power by the voltage. In this example, the current would work out at 13 A.

How much kw in ikva?
Do you mean 1 kVA? kVA (thousands of volt-ampere) is the same as kW (thousands of watt) - assuming the current and the voltage are in phase (in other words, assuming the power factor is equal to 1), which is usually a good approximation.
What is the kilowatt output of an electric heater that has an ampere draw of 50 and a voltage source of 240 volts?
At 240 v and 50 amps the power is 12 kW because 240x50 is 12,000.
How do you convert 5kW to amps if your voltage is 120?
P, the power in kW (kilowatts) is related to V (the supply voltage) and I (the current in amps) by the Power Law: P = V x I So, to get the current: I = P / V If you have something that uses 5 kW (which is the same as 5000 watts) and the source voltage is 120 V, then the current drawn in amps = 5000 / 120 = 41.67 amps.
What is the kilowatt output of an electric heater that has an ampere draw of 50 a and a voltage source of 208 volts?
The watts is the volts times the amps So 208 x 50 watts, or 10.4 kW.
Two and an half kva equals how many ampere?
2.5 kVA means 2500 VA (volt-ampere). To calculate the amperes you need the voltage. 2.5 kVA x cos (phi) = 2.5 kW (kilowatts) if phi is 0 or power factor (phi) is unity.
What is ampere rating of an electrical kettle?
Divide its power rating by its voltage rating. These ratings are found on its nameplate. For example, a 3-kW kettle rated at 230 V will draw a current of approx. 13 A.
