It depends on the current requirement. Specify an application or describe what is being powered by the 12 V to get an answer.
Not without a lot of very expensive equipment
How much current? Volts/Amps = Ohms. In your case Volts = 1.5
Input: AC 100-127 Output: DC 12V
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
Definitely not it could be dangerous. AC and DC can't be interchanged in general.
how to know dc cable sizes
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.
12v dc to 3v dc
The correct size of cable depends on the length of the cable run, as well as the voltage and current. Another consideration is what voltage loss is acceptable ? Safest answer would be to use a cable sizing table or online tool: http://www.solar-wind.co.uk/cable-sizing-DC-cables.html Hope that helps. G.

what is the diference between 12V 15A DC coil & 12V 10 amps DC coil
using dc-dc converter
No, you cannot.
If you want to convert 24v AC into 12v Ac, it's simple. Just get a transformer to convert 24 volts into 12 volts. This is called a stepdown transformer. If you want to convert 24v DC into 12v DC, it's more complicated. First you have to change the 24v DC into 24v AC by a switching converter that changes DC into AC. Then you would use a stepdown transformer as in the former example. Once the 24v AC is converted to 12v AC, then you use a rectifier bridge to change the 12v AC into 12v DC.
