In ideal conditions, about 6W
Amps x volts = watts
500ma = 1/2 amp (1000ma to 1a)
0.5 X 12V = 6W
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.
To calculate the current (in milliamps), you can use the formula: Current (in mA) = Power (in watts) / Voltage (in volts). In this case, Current = 2 watts / 12 volts = 0.167 amps. To convert this to milliamps, multiply by 1000: 0.167 amps * 1000 = 167 mA. Therefore, there are 167 milliamps in a 12V DC, 2W DC circuit.

To calculate the amperage, we can use the formula: Amps = Watts / Volts. In this case, it would be 70 watts / 13.8 volts ≈ 5.07 amps. So, with 70 watts and a voltage of 13.8 volts DC, the amperage would be approximately 5.07 amps.
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device

DC 12V power supply can convert 110/220V AC power source to 12V 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
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.
