Watts = current x volts, so you have to multiply Kw value by 1000 to get watts, then divide by the applied voltage. examples.
2Kw kettle (U.S) current = 2 x1000 divided by 120, or 16.7 amps
2Kw kettle (UK) current = 2 x1000 divided by 240 or 8.35 amps
100 watt car amplifier current = 100 divided by 12 volts = 8.5amps
USB 3.1 (C) can deliver a power output of up to 100 watts (20 volts and 5 amps).
100 amps to a 3 phase load. Power = 100A x Voltage x 1.73 ((line to line voltage)(1.73=SQRT(3)). 173 amps to each of 3 single phase (line to line) loads. Power = 173A x Voltage (line to line voltage). or... 100 amps to each of 3 single phase (line to neutral) load. Power = 300A x Voltage (line to neutral voltage). Example: - 3 phase, 480v, 100amp to a 3 phase heater. 100A x 480V x 1.73 = 83040 watts. - 3 single phase 480v (L-L voltage) heaters, 100amp. 173A x 480V = 83040 watts. - 3 single phase 277v (L-N voltage) heaters, 100amp. 300A x 277V = 83100 watts.
Generators are rated in watts because watts are the scale on which energy is measured.
It depends on what the voltage is: A Watt is a unit of power described as "1 ampere of current pushed by 1 volt of Electro-motive force", therefore 1W = 1A x 1V. 1 kW is a "kilowatt" or 1000 Watts. Using the above formula, and a little algebra, you can find the current required to deliver any amount of power depending on the applied voltage: Current = Power / Voltage; symbolically expressed as I = P / V examples: * 9.5kW x (1000W/kW) / 120v = 79.2 amps * 9.5kW x (1000W/kW) / 240v = 39.6 amps * 9.5kW x (1000W/kW) / 480v = 19.8 amps (Notice how raising the voltage reduces the required current?)
for 1 hp we cnt say the amps why because hp will mention the speed in never will differ but comparatively amps (load) will differ dip pends upon the voltage (380,220,440)W = V * I / I = W / V
To convert watts to amps, you can use the formula: Amps = Watts / Volts. In this case, to convert 200 watts at 12 volts to amps, it would be: 200 watts / 12 volts = 16.67 amps. So, 200 watts at 12 volts is approximately 16.67 amps.
To convert amps to watts, you need to know the voltage of the circuit. The formula to calculate watts is: Watts = Amps x Volts. Multiply the current in amps by the voltage in volts to get the power in watts.
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
Get the volts and multiply that by the amps. This will give you the watts.
Watts are the product of amps x volts.
To convert watts to amps at 120 volts, use the formula: Amps = Watts / Volts. For 1500 watts at 120 volts, the calculation would be: 1500 watts / 120 volts = 12.5 amps.
power equals current times voltage 50w=(I)110v so 50w\110v = I .454 amps
It's watts divided by volts equals amps. Example: 1200 watts at 120 volts is 10 amps. To get the watts if you know the amps, multiply the amps times the volts. 10 amps at 120 volts is 1200 watts.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
I t depends. Watts = Amps times volts. 40 amps x 120 volts =4800 watts or 40 Amps x 12 volts = 480 watts.
The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.
