40Amps to Watts Conversion. As can be concluded from the formulas, in order to convert the units 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 = 40 A × 110 V = 4400 W. AC, Single Phase: P = 40 A × 0.5 × 110 V AC2= 2200 W. AC, Three Phase, Line to Line Voltage: AC2P

90Watts at 5 volts is 18 Amps, so you need a 5 volt power supply that can supply at least 20 Amps - perhaps 25 Amps to allow a safety margin. Share. Cite. Follow answered May 1, 2020 at 1:31. Peter Bennett Peter Bennett. 58.4k 1 1 gold badge 48 48 silver badges 130 130 bronze badges \$\endgroup\$
500Watts to Amps Conversion. From our formulas follows that in order to convert 500 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 = 500 W / 110 V = 4.55 A. AC, Single Phase: I = 500 W / (0.5 × 110 V) = 9.09 A. AC, Three Phase, Line to Line Voltage: I = 500 W / (√
51 Amps to Watts Conversion. As can be concluded from the formulas, in order to convert the units 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 = 5.1 A × 110 V = 561 W. AC, Single Phase: P = 5.1 A × 0.5 × 110 V AC2= 280.5 W. AC, Three Phase, Line to Line Voltage: AC2P
