AC three phase kilowatts to amps calculation formula
- I = 1000 × P / (√3 × PF × VL-L )
- amps = 1000 × kilowatts / (√3 × PF × volts)
- A = 1000 × kW / (√3 × PF × V)
- I = 1000 × 0.33kW / (√3 × 0.8 × 110V) = 2.165A.

How many kWh are in a amp?
kWh to Ah Conversion Formula The electrical charge in amp-hours is equal to the energy in kilowatt-hours times 1,000, then divided by the voltage. For example, let’s convert 5 kWh at 120 V to Ah. You might also want to convert watt-hours to milliamp-hours.
How do you convert amps to kW?
AC three phase amps to kilowatts calculation formula
- P(kW) = √3 × PF × I(A) × VL-L(V) / 1000.
- kilowatt = √3 × PF × amp × volt / 1000.
- kW = √3 × PF × A × V / 1000.
- P = √3 × 0.8 × 3A × 110V / 1000 = 0.457kW.
How many kWh does a 12V battery produce?
How many Watt-Hours in a battery?: Watts are pretty simple – it is just battery voltage times amp-hours. A 12 volt 105 AH battery can supply (under perfect conditions and to 100% discharge) 12 x 105, or 1260 Watt-hours ( 1.26 kWh ).
How do you convert kW to kWh?
To get the number of kWh, you just multiply the number of kW by the number of hours the appliance is used for. For example, a device rated at 1500 W that’s on for 2.5 hours: 1500 ÷ 1000 = 1.5. That’s 1.5 kW.
How do you calculate kW from current?
Single Phase AC – kW to amps For any single-phase AC circuit, Current, I = 1000 x kW / (Vac x P.F.) Therefore, amps can be calculated from AC – kW by dividing kW by the product of the RMS value of applied AC voltage and power factor and multiplying it by 1000.
How do you calculate kW in a 3 phase circuit?
For 3-phase systems, we use the following equation: kW = (V × I × PF × 1.732) ÷ 1,000.
How do I calculate current?
The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).
How many kilowatts does it take to run a house?
According to the EIA, in 2017, the average annual electricity consumption for a U.S. residential home customer was 10,399 kilowatt hours (kWh), an average of 867 kWh per month. That means the average household electricity consumption kWh per day is 28.9 kWh (867 kWh / 30 days).
How do I convert watts to kWh?
To find the kilowatts used by an appliance, you simply divide the watts listed on the appliance by 1,000 (the number of watts in a kilowatt) and then multiply by the hours used. For example:You used a 400 watt radio for one hour today.
