In ideal conditions, about 6W
Amps x volts = watts
500ma = 1/2 amp (1000ma to 1a)
0.5 X 12V = 6W
Watts aren't consumed per hour, as Watts are defined as joules per second. The wattage of a described unit would be 12 times .5, or 6 watts.Ê
12 V DC, 18 VA (watts) how many amps? Formula: amperage I = power P (VA) divided by voltage V. So, amperage I = 18 watts / 12 volts = 0.083 amperes.

No, 3200 ma = 3.2 amps
Watts = Volts * Amps Therefore: 70 Watts / 13.8 Volts = 5.07 Amps
Input: 110-240V AC, Output: 12V DC, 3.7A

DC 12V power supply can convert 110/220V AC power source to 12V DC.
1farad 20v dc
if you have 12v dc then you can use a 4 ohm resistor
Battery chargers have a 12v DC output.
500 milliamp = 1/2 amp. Have to know the wattage of the lamps or the resistance of one lamp to give an answer.
Power = volts x amps, so your example will be 12 x 0.5 = 6 watts. (500mA = 0.5 amp) Note we don't talk of 'watts per hour', it is just watts. 1 watt = 1 joule per second
12v dc to 3v dc
No, 3200 ma = 3.2 amps
Yes you can but for devices use 12 v and 500 ma( 0.5 a) <<>> No, the output of the 500 mA power supply will be too small for a device that requires 700 mA to operate. It can be done the other way around though, a 700 mA power supply will operate a device that only requires 500 mA with 200 mA to spare.
Watts = Volts * Amps Therefore: 70 Watts / 13.8 Volts = 5.07 Amps
