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
Amperes are a measure of current. Volts are a measure of electrical pressure (voltage) To convert one to the other you need to take the resistance to flow into account. current (in amperes) = voltage (in volts) / resistance (in ohms) voltage (in volts) = current (in amps) x resistance (in ohms)
Volts cannot be directly converted into watts as they measure different aspects of electricity. Volts must be multiplied by the number of amps to determine the number of watts.
1ma = .001amps
watts = amps * volts
Take your voltage (ie 110 in NA) and multiply the amperage to get your wattage.
Amps * Watts = Volts
OR, from high school algebra
Amps = Volts/Watts
Watts = Amps x Volts
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?)
The relationship between horsepower (HP) and amps depends on several factors, including the voltage of the electrical system and the efficiency of the device or motor being measured. The relationship can be calculated using the formula: Power (in horsepower) = Voltage (in volts) xCurrent (in amps)/746 Where: Power is measured in horsepower (HP) Voltage is measured in volts (V) Current is measured in amperes (amps) The number 746 is a conversion factor used to convert watts (W) to horsepower (HP). So, if you know the voltage and current of an electrical device, you can use this formula to calculate the power in horsepower. Conversely, if you know the power in horsepower and the voltage, you can rearrange the formula to solve for the current in amps. It's important to note that this formula assumes a certain level of efficiency and power factor for the device being measured. In real-world applications, the actual relationship between horsepower and amps may vary based on factors such as motor efficiency, power factor, and other electrical characteristics.
Amps are units of current, watts are units of power. Watts are the product of Amps times Volts. Watts = Amps x Volts.
To convert amps into watts a voltage is needed. Watts = Amps x Volts.
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
Amps = Watts/Volts, or Amps = Sq Root of Watts/Resistance.
You multiply volts by amps to get watts. What are your amps?
Watts are the product of amps x volts.
Get the volts and multiply that by the amps. This will give you the watts.
Watts = Amps x Volts. Amps = Watts/Voltage. Amps = 2500/apply voltage here.
Only when the load is purely resistive.
9000 watts is zero amps. Amps are the product of amps times volts. Without a voltage stated an answer can not be given. 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.
Watts = amps x volts, Amps = Watts/Volts, 65/240 = .27 amps or 270 milliamps
