There are zero kilowatts in amps. A voltage value has to be supplied before an answer can be given. I = W/E. Amps = Watts/Volts = 12000/Volts. Alternatively, you could state the resistance, from which the amps are determined from P/R = I2.
The V stands for volts and A is amps. If for example you have a 12kVA device and are running off a voltage of 120 volts then Amps = 12000/120 = 100. You then use the calculated amps in a wire size table to get the correct size.
There are zero amps in 50 watts. The equation for amperage is, I W/E. Amps = Watts / Volts. As you can see if there is no voltage stated the amperage can not be calculated.
In general, multiply the (rms) current by the (rms) voltage to get the power. If the voltage to the appliance is 120 Volts, then the power of 4.2 Amps is 504 Watts. If the voltage is 240 Volts, then 1008 Watts. Note: To be technically accurate, you must also multiply the cosine of the phase-angle between current and voltage. For any typical appliance, this is 1 and can be ignored. <<>> There are zero watts in 4.2 amps. Watts = Amps x Volts. Without a voltage stated the wattage can not be calculated.
At 120 volts it will pull 4.166 amps. At 240 volts it will pull 2.08 amps.
volts X amps
The device consumes 84 watts of power. This can be calculated by multiplying the voltage (12 volts) by the current (7 amps). So, 12 volts x 7 amps = 84 watts.
volts X amps
Amps and volts are two separate parts of power measurement and do not convert into each other. Multiplying amps times volts will give you the measurement of wattage.
Power is calculated by multiplying Volts x Amps, hence 60 Volts and 2 Amps will give 120 Watts. Energy is Power over a length of time. So if you use this device for say 2 hours you will consume 240 Watt Hours of Energy.
The power (in watts) can be calculated by multiplying the current (in amps) by the voltage (in volts). In this case, 10 amps at 12 volts would result in 120 watts of power (10A * 12V = 120W).
The wattage would be 500 watts. This is calculated by multiplying the amperage (5 amps) by the voltage (100 volts), resulting in 500 watts of power.
Multiplying 400 volts by 45 amps would give you a power output of 18000 watts, which is equivalent to 18 kilowatts (kW).
Watts can be calculated by multiplying the voltage (V) by the current (I) in amperes. The formula is: Watts = Volts x Amps. For example, if you have a circuit with a voltage of 120V and a current of 5A, the power output would be 600 watts (120V x 5A = 600W).
To calculate watts, you need to multiply the voltage (in volts) by the current (in amps). For the 208 volts, 8 amps heating element: Watts = 208 volts * 8 amps = 1664 watts For the 110 volts, 8 amps heating element: Watts = 110 volts * 8 amps = 880 watts
Power (in watts) is calculated by multiplying the voltage with the current. In this case, 5 amps running on 10 volts would use 50 watts of power.
If the wattage of a load is known then the current can be calculated. Watts equals amps times volts. You would use the following formula, Amps = Watts/Volts.
