100 Watts to Amps

Welcome to 100 watts to amps, which stands for 100 watts to amperes.

If you have been wondering how many amps is 100 watts, then you have come to the right page, too.

To obtain 100 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 100 watts to amps with alternating current (AC), we additionally must know the power factor, the number of phases and perhaps the voltage type.

Convert 100 Watts to Amps

To convert 100 watts to amps, thereby changing power (P) to current (I), consider the criteria below. Next apply the corresponding 100 watts (W) to amps (A) formula further down.

For the conversion of 100 watts to amps check whether your electric current is of type direct or alternating flow of electric charge, as explained in details on our article Watts to Amps.

For alternating currents, the 100 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 100 watts to amps, (√3) and 3, respectively.

  • DC: I(A) = 100 W / V(V)
  • AC, Single Phase: I(A) = 100 W / (PF × V(V))
  • AC, Three Phase, Line to Line Voltage: I(A) = 100 W / (√3 × PF × VL-L(V))
  • AC, Three Phase, Line to Neutral Voltage: I(A) = 100 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 = 100 W.

Here you can find 100 amps to watts, along with useful information.

The next paragraph exemplifies a number of 100 watts to amps calculations.

Next, we will answer what is the current in amperes if the power consumption is 100 W and the voltage supply is 110 V?

100 Watts to Amps Conversion

From our formulas follows that in order to convert 100 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 = 100 W / 110 V = 0.91 A
  • AC, Single Phase: I = 100 W / (0.5 × 110 V) = 1.82 A
  • AC, Three Phase, Line to Line Voltage: I = 100 W / (√3 × 0.5 × 110 V) = 1.05 A
  • AC, Three Phase, Line to Neutral Voltage: I = 100 W / (3 × 0.5 × 110 V) = 0.61 A

Instead of applying the formulas use our watts to amps converter. Insert, for example, 100 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 100 watt to amp.

100 Watts to Amperes

If you have been looking for 100 watt how many amps, then you have found all the information here on our website. Frequently asked question in the context of our post are:

  • How many amps in 100 watts?
  • 100 watts how many amps?
  • How much is 100 watts in amperes?
  • How many amps in a 100 watts?
  • How many amps per 100 watts?


As you know, the answer to the equation 100 watt = amp depends on various parameters:

For example, how many amps is 100 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) 0.42, 0.83, 0.48 and 0.28 amperes, respectively.

Likewise, 100 watts at 220 volts to amps is 0.45, 0.91, 0.52, 0.3 A. Finally, 100 watts to amps 120 volts = 0.83, 1.67, 0.96 and 0.56 amperes.
