No, because 100 v at 1 amp is a supply of 100 watts of power. It could be turned into a 25 v supply using a switch-mode voltage converter, but the available power would still be theoretically no more than 100 w, which is 4 amps at 25 v. In practice it would be slightly less.

∙ 10y agoYes, it is possible to convert voltage and current using a transformer or a converter. In this case, you could step down the voltage from 100 VDC to 25 VDC while increasing the current from 1 Amp to 10 Amps using the appropriate transformer or DC-DC converter. Make sure to choose a device that can handle the power requirements of the converted circuit.
For a 100 amp 12VDC circuit, you would typically use 2/0 AWG (00 AWG) wire to ensure proper conductivity and safety. This size of wire is rated for up to 150 amps in most applications, providing a good margin for the 100 amp load. Be sure to consult local electrical codes and standards for specific requirements.
For a 125 VDC battery feeding a 200 amp main breaker, you should use at least 2/0 AWG wire size to ensure proper current carrying capacity and safety precautions. Larger wire sizes could be used if the distance between the battery and breaker is substantial to minimize voltage drop.
As watts equals volts times amps (ohms law simplified) you are missing part of the equation.. Let's say you are asking about how many watts is 1 amps at 12v then... If W = V x A then 1A at 12v = 12 watts
No, you cannot use a 50 amp automotive relay with a 12V DC coil to control 12V AC 500 watt halogen lighting. Automotive relays are designed to work with DC power, not AC power. Additionally, the amp rating of the relay refers to its capacity for DC load, not AC load. You should use a relay specifically designed for AC applications with the appropriate voltage and current ratings.
"VDC" on jewelry stands for "Vermeil on Dead Copper." This indicates that the piece is made of a base metal (copper) plated with a thick layer of gold (vermeil). It signifies that the item is not pure gold, but rather gold-plated.
Amps is amps be it DC or AC.

The depends upon what you are trying to work out.
Yes, there will be no problem with this adapter. The 1 amp device will only be drawing half of what the adapter can produce.

Both are equally as dangerous, as 250-volts is more than enough to exceed the .1 amp (100 milli-amps) needed to cause your heart to stop beating correctly. DC electrical current cause more sever burning than AC current does, but when the voltage is as high as 250 V, it will not matter much which type of current it is... both have the potential to kill you.
See discussion page below.
In a 12VDC circuit with a 1K load, there will be 12ma of current. (Ohm's law: Volts = Amps * Ohms, so Amps = Volts / Ohms.)
It depend on what the load of the device that plugs into it is. The mA rating is the maximum amount of amperage that the adapter can produce. The 500 mA adapter will produce about a half amp whereas the 1200 mA adapter outputs 1.2 amps. So one is about three times larger that the other. Check the device that you are trying to power for a mA load and that will tell you whether you can use it on the 500 mA adapter.
