Welcome to 45 watts to amps, which stands for 45 watts to amperes. If you have been wondering how many amps is 45 watts, then you have come to the right page, too. To obtain 45 watts in amps in case of direct current (DC), we only have to know the potential difference in volts (V). To be able to transform 45 watts to amps with alternating current (AC), we additionally must know the power factor, the number of phases and perhaps the voltage type.
Convert 45 Watts to Amps
To convert 45 watts to amps, thereby changing power (P) to current (I), consider the criteria below. Next apply the corresponding 45 watts (W) to amps (A) formula further down.
For the conversion of 45 watts to amps check whether your electric current is of type direct or alternating flow of electric charge, as explained in details on our home page.
For alternating currents, the 45 watts amps transformation is different for a single phase and a three phase system; the power factor is needed in both cases.
In case of the three-phase electrical generation, line to line voltage and line to neutral voltage require different constants to convert 45 watts to amps, (√3) and 3, respectively.
- DC: I(A) = 45 W / V(V)
- AC, Single Phase: I(A) = 45 W / (PF × V(V))
- AC, Three Phase, Line to Line Voltage: I(A) = 45 W / (√3 × PF × VL-L(V))
- AC, Three Phase, Line to Neutral Voltage: I(A) = 45 W / (3 × PF × VL-0(V))
In an alternating current circuit, the power factor (PF) is the quotient of real power / apparent power with a value in between 0 and 1: 0 ≤ PF ≤ 1; real power here is = 45 W.
The next paragraph exemplifies a number of 45 watts to amps calculations, and there you can also locate our calculator. Note that all of our conversions are rounded two decimals.
Next, we will answer what is the current in amperes if the power consumption is 45 W and the voltage supply is 110 V?
45 Watts to Amps Conversion
From our formulas follows that in order to convert 45 watts in amps we must know the voltage. Assumed the PF is 0.5, and supposed the voltage is 110 V, we get these result:
- DC: I = 45 W / 110 V = 0.41 A
- AC, Single Phase: I = 45 W / (0.5 × 110 V) = 0.82 A
- AC, Three Phase, Line to Line Voltage: I = 45 W / (√3 × 0.5 × 110 V) = 0.47 A
- AC, Three Phase, Line to Neutral Voltage: I = 45 W / (3 × 0.5 × 110 V) = 0.27 A
Instead of applying the formulas use our watts to amps converter. Insert, for example, 45 for the power in watts; your voltage in volts is also required for all conversions.
Depending on your selected current and the number of phases, the power factor as well as the voltage type may also have to be entered to transform 45 watt to amp.

- How many amps per 45 watts?
As you know, the answer to the equation 45 watt = amp depends on various parameters:
For example, how many amps is 45 watts at 240 volts has only one result for direct current, abbreviated as DC, but three possibilities in case of AC, short for alternating current.
In the order of the drop-down menu of our converter, and in the sequence of our explanations and formulas above, they are (PF=0.5) 0.19, 0.38, 0.22 and 0.13 amperes, respectively.
Likewise, 45 watts at 220 volts to amps is 0.2, 0.41, 0.24, 0.14 A. Finally, 45 watts to amps 120 volts = 0.38, 0.75, 0.43 and 0.25 amperes.
