mA or current is only an element of Watts. Watts= voltage x current (amps). So multiply 0.650 (650mA) by the supply voltage to get the wattage. e.g. if its a 12 volt supply you get 12 x 0.650 = 7.8 watts

To convert milliamps (mA) to watts, you need to know the voltage at which the current is flowing. The formula to calculate power (watts) is power (W) = current (A) x voltage (V). So without knowing the voltage, it is not possible to directly convert 650 mA to watts.

How many watts does a Dyson vacuum use?
The wattage of a Dyson vacuum cleaner can vary depending on the model. On average, Dyson vacuums typically range from 300 to 1400 watts, with most popular models falling between 600 to 1200 watts.
How many watts are in 200 mA?
To convert milliamps (mA) to watts, you need to know the voltage as well. The formula for this conversion is: Watts = Volts x Amps. If you provide the voltage, I can help you calculate the wattage.
How many Watts does a xerox machine use?
A Xerox machine typically uses around 600 to 1,500 watts when in operation, depending on the specific model and functions being used.
How many watts is 500ma?
A half of an amp equals 500 mA.ma or mA means milliAmp or milliAmpere. As milliAmpere and Ampere are related as: 1mA = 1*10^-3 A = 0.001 A, so you can express 500 ma as 500*0.001 A = 0.5 A. See relarted linksbelow.
How many amps is needed for 72 watts?
One mA (milliampere) is simply one one-thousandth of one ampere (amp). So, 72 mA is 0.072 amps, or seventy-two thousandths of one amp.

What size wire do you need for 650 watts?
To answer this question a voltage needs to be stated. Wire is sized by the amount of amperage the load takes. W = Amps x Volts. Amps = 650/ volts.
How many amps is needed for 72 watts?
One mA (milliampere) is simply one one-thousandth of one ampere (amp). So, 72 mA is 0.072 amps, or seventy-two thousandths of one amp.
How many tens are there in 650?
650 ÷ 10 = 65
How many watts does a radio use?
The power consumption of a radio can vary, but most radios typically use between 5-50 watts when playing music at a moderate volume. It's recommended to check the specific power usage of your radio model for a more accurate estimate.
How many amps does 660 watts draw?
This depends on the voltage ... amps = watts / volts 660 W / 110 V = 6 amps 660 W / 220 V = 3 amps 660 W / 330 KV = 2 mA
