Power, in 'watts'.
The amperage of a motor is governed by the voltage that the motor operates on. Without a voltage given, an answer can not be given.
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.
Power is obtained using the equation: Power (Watts) = Voltage (Volts) x Current (Amps) To convert to Watts to Kilowatts (kW), simply divide by 1000 (or shift the DP left by 3 places). eg. 5000W = 5kW Bringing these together: Kilowatts = ( Volts x Amps ) / 1000
The power dissipated by a circuit with a voltage of 12V and a current of 3A is 36W. Watts is Volts times Amps.
All power adapters have to match the Wattage, Voltage and Amps exactly. So you have to look on the adapter on both of the power adapters and see if they match. If you use a power adapter that has more power than is needed you will fry the motherboard so be carefull. The wattage, voltage and amps are on the adapter..
No. Your power supply must be able to supply rated voltage (12 volts) and rated current (3 amps).
No, the voltage is wrong. The device needs an adapter that only produces 5 volts. The device that you need may state on it 2500 mA instead of 2.4 amps
If you know the voltage you can calculate the amps. . Ampere I = power P / voltage V .
Since power = current x voltage, you would divide the power (watts) by the voltage. The answer would be 1/10 amps or .10 amps.
voltage X amps = wats
To calculate watts from amps, you need to know the voltage of the circuit. The formula to convert amps to watts is: Watts = Amps x Volts. So, if the voltage is 120V, then 60 amps would be 7200 watts (60 x 120).
Look on the light bulb for the voltage and the power in watts. Then divide the watts by the voltage and that gives the amps. Some CFL bulbs also state the current as well as the voltage and power, which is because they can have a poor power factor.
To calculate the amperage, you need to know the voltage. The formula to calculate amperage is: Amps = Watts / Volts. For example, if the voltage is 120V, then the amperage for 32 watts would be 0.27A.
current is the other factor. power (wattage) is the product of current (amps) and voltage
Yes, the adaptor allows load currents of 1200 amps or less, and 500 amps is included in that. The voltage of a supply stays constant, the current that flows is determined by what power the appliance needs to run.
Amps are not directly convertible to horse power, which is a measure of power. Power is current times voltage. Therefore on a 240 v supply, 750 amps equals 180,000 watts. One horse power is 746 watts.
