It depends on the current requirement. Specify an application or describe what is being powered by the 12 V to get an answer.
Depending on how it's used, it can mean air conditioning, or it can mean alternating current (as electrically powered) as opposed to battery powered (DC, which is direct current). Or Animal Crossing

LEDs are powered by direct current (DC) power. They require the voltage and current that they are built for. LEDs are diodes which means that current will only flow one way through them, if you wire up a LED backwards it will not function.
With electricity provided from wall current or from batteries.
It is a current :)
A powered USB hub is needed if you have a lot of items to be plugged in and charging. iPods seems to need a powered hub to have enough current to charge fully.
It will not be possible to measure current unless the circuit is powered and operating.
it is powered by alternating current, or electricity
a current.
yes
The conversion is Potential to Kinetic.
