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.
A 3/0 copper conductor with an insulation factor of 90 degrees C is rated at 210 amps.
A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps consecutively. As for the voltage, wire is usually rated in 300, 600 and 1000 volts. Any three of these insulations factors will handle 12 VDC.
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
95 VDC is zero 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.
Amps is amps be it DC or AC.
600 VDC.
A 3/0 copper conductor with an insulation factor of 90 degrees C is rated at 210 amps.
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.
12 Volts 18 amps
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.
The transformer for n HO scale train has a primary voltage of 115 volts. There is a tap off for accessories that is 17 volts AC and a rectified DC voltage to apply to the track at 10 VDC at 1 amp.
Shova VDC's population is 7,279.
