How do you calculate amps from watts?
How do you calculate amps from watts?
Amps calculation with line to line voltage
- I(A) = P(W) / (√3 × PF × VL-L(V) ) So amps are equal to watts divided by square root of 3 times power factor times volts.
- amps = watts / (√3 × PF × volts) or.
- A = W / (√3 × PF × V) Example.
- I = 330W / (√3 × 0.8 × 110V) = 2.165A. Amps calculation with line to neutral voltage.

How many watts is 3.7 amps?
3.7 amps equals 444 watts with 120 volts DC.
How do you convert watts to amps in a calculator?
How to convert watts to amps. To find the amps, you work backwards with Watt’s Law and divide the wattage by the volts: Current (I) = Power (P) ÷ Voltage (E) So…. amps = watts ÷ volts. Example: 600 watts are being sent at 120 volts.
How are watts and amps related to each other?
The current I in amps is equal to the square root of the power P in watts multiplied by the resistance R in ohms. It is not possible to convert watts directly to amps without also knowing voltage or resistance.
How to convert amps to Watts in rapid table?
Select current type, enter current in amps, voltage in volts, power factor for AC circuit and press the Calculate button (DC = Direct Current, AC = Alternating Current): * Use e for scientific notation.
How to calculate phase current in Watts and amps?
Calculation with line to line voltage. The phase current I in amps (A) is equal to the power P in watts (W), divided by square root of 3 times the power factor PF times the line to line RMS voltage V L-L in volts (V): I (A) = P (W) / (√3 × PF × V L-L(V) ) The power factor of resistive impedance load is equal to 1.
What is the formula for converting watts to amps?
Converting watts to amps can be done using the Watt’s Law formula, which states that I = P ÷ E, where P is power measured in watts, I is current measured in amps, and E is voltage measured in volts.
How do you calculate watts from amps?
You calculate watts by multiplying the amps by the line voltage, typically 120 V in the United States. For instance, if your portable electric heater’s label says it draws 8.35 amps when operating, multiply 8.35 amps by 120 V to get about 1,000 watts of demand.
What’s the difference between amps, volts and Watts?
- Amps represent the volume of water present.
- Voltage represents the water pressure
- Watts are the energy created by the closed system that powers the mill.
- Ohms represent the amount of resistance created by the size of the pipe.
What is the best way to convert amps into Watts?
- V For example: If you want to know the power consumption in watts for an appliance with a current of 3
- then real power in watts will be given in terms of a power factor (PF) multiplied
- Three-Phase AC Amps to Watts
