Welcome to 4 amps to watts, short for 4 amperes to watts.
You have also come to the right page if you have been wondering how many watts is 4 amps.
To get 4 amps in watts in case of direct current (DC), the only thing we have to know is the potential difference in volts (V).
In contrast, for the transformation of 4 amps to watts with alternating current (AC), we additionally have to know the power factor, the number of phases and perhaps the voltage type.
Convert 4 Amps to Watts
To convert 4 amps to watts, by that changing current (I) to power (P), first learn about the criteria. Then apply the corresponding 4 amps (A) to watts (W) formula further down.
For the conversion of 4 amps to watts, find out if your electric current is of type direct or alternating flow of electric charge, as explained in details on our article Amps to Watts.
In case of an alternating current, the 4 amps watts transformation is different for a single-phase and three-phase system. However, the power factor is needed for both.
Moreover, for a three phase electrical generation, line to line voltage and line to neutral voltage require a different constant to convert 4 amps to watts, (√3) and 3, respectively.
- DC: P(W) = 4 A × V(V)
- AC, Single Phase: P(W) = 4 A × PF × V(V)
- AC, Three Phase, Line to Line Voltage: P(W) = 4 A × √3 × PF × VL-L(V)
- AC, Three Phase, Line to Neutral Voltage: P(W) = 4 A × 3 × PF × VL-0(V)
In an alternating current circuit, the power factor (PF) is equal to the real power P = I2R divided by the apparent power, 0 ≤ PF ≤ 1; here I = 4 A, R = resistance.
In the next section we will show you some 4 amps to watts calculation examples.
Next, we’ll answer what is the power consumption in watts if the current is 4 A and the voltage supply is 110 V?
4 Amps to Watts Conversion
As can be concluded from the formulas, in order to convert 4 amps in watts the voltage must be known, too. Supposed the PF is 0.5, and assumed the voltage is 110 V, we obtain these result:
- DC: P = 4 A × 110 V = 440 W
- AC, Single Phase: P = 4 A × 0.5 × 110 V AC2= 220 W
- AC, Three Phase, Line to Line Voltage: AC2P = 4 A × √3 × 0.5 × 110 V = 381.05 W
- AC, Three Phase, Line to Neutral Voltage: P = 4 A × 3 × 0.5 × 110 V = 660 W
In place of employing the formulas, utilize our amps to watts converter. Enter, for instance, 4 for the current in amps, and note that in any case your voltage in volts is also required.
Subject to your selected current and the number of phases, in addition to the power factor, the voltage type may has to be inserted as well to transform 4 amp to watt.
