Watts = Volts x Amps. 12 megawatts = 12,000,000 watts. You need to know current to calculate the voltage.
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
Watts are not deadly but it would take 12 micro-watts through the heart to kill someone.
Watts is volts times amps, so 12 x 30 = 360 watts
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
There are zero milliamps in 12 watts.
72 watts
Watts = Volts x Amps. 12 megawatts = 12,000,000 watts. You need to know current to calculate the voltage.
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
Watts are not deadly but it would take 12 micro-watts through the heart to kill someone.
Voltage of the pump (12) multiplied by the current draw = the watts used. This would be 12 watts if the current was 1 amp, 24 watts if the current is 2 amps, and 36 watts if the current is 3 amps, and so on...
On a 12-volt system 1.6 amps is 12x1.6 watts, 19.2 watts
i can't find any reliable information (still looking!), but i believe the 12" memphis mojos are about 1000W average/2000W max. 4000W is likely a good way to ruin $300-600 of awesome speakers.
14.4 watts
The estimated watts of a vacuum cleaner needed is 7 to 12 amps or 144 watts.
Watts is volts times amps, so 12 x 30 = 360 watts
