What the fuck I am talking about, is that transformers only output current as the magnetic field in the coil collapses, and as such, transformers only work with ac (field collapses as the current alternates) or pulsing dc current (field collapses after each pulse). You cant run non pulsing DC through a transformer
12V DC -> 12V pulsing DC -> 9.5V pulsing DC -> 9.5V DC.
When I said everything is designed to plug into our 120 AC plug in's is because it is, physically the two prong (or three if it has the ground) plug in is the standard in north america, the physical plug, not the voltage. An outlet is a physical connection, you can run any type of electricity through any plug as long as it can support the amount of electricity you are putting through it without lighting on fire (as long as the metal is thick enough). When i said you dont need an adapter, I meant a PHYSICAL adapter.
and the reason we use AC, is becuase as I have previously stated, you cant transform DC to high voltage, and its easier to make AC DC than make DC AC. (you need to transform it to high voltage to prevent line loss. line loss is a function of high voltage low amperage, not DC vs AC like you stated,)
Also, I don't need to link to the Wikipedia pages about electrical devices, because I learned it in school, not ten minutes ago on the web you jackass.
buuut, since you dont seem to be able to understand my wording, lets try someone elses. heres a simply worded explanation from the web.
"Let's look at a transformer first. Transformers are essentially two coils that are wrapped (wound) around a common core. The primary is supplied with a changing voltage. This develops a changing magnetic field in the core. And this changing magnetic field in the core "sweeps" the secondary windings and generates a voltage in those secondary windings. The changes in the primary due to the changing voltage are inductively coupled into the secondary to generate voltage there.
The general answer to why a transformer doesn't work on a DC supply is that a DC voltage doesn't "change" and cause changes in the magnetic field in the core, and, thereby, cause changes in the voltage in the secondary windings. When we "turn on" the DC (direct current), a field will be built in the core, it will sweep the secondary windings and deliver a "pulse" as the field is built. But then the secondary voltage will drop to zero after the pulse. This is because there is a static magnetic field around the secondary windings, and a static field will not sweep the windings and generate a voltage. There will be no secondary voltage.
It is possible to generate pulses of voltage in a transformer by pulsing a DC voltage supplied to the primary. The ignition coil in an automobile works in this way. The 12-volt supply is pulsed to the coil to generate the high voltage to fire the spark plugs. It is possible to get a transformer to work on DC. But, in general, transformers need a dynamically changing voltage supplied to them to cause the changing magnetic field in the core. This changing magnetic field will sweep the secondary windings and generate a changing voltage there. AC (alternating current) works really well for this application, and we use this idea in the power grids around the world."
Almost everything you said was either wrong or irrelevant and you made an ass of yourself trying to tell me I was wrong, or at least to anyone reading who knows anything about electricity. You don't know what you are talking about, either learn more before you respond or stop trying.
