How do you produce 12V adapter?
From what? If you need 12VDC for temporary use, there is a very good 12VDC source in your PC power supply.
How do you drop 12vdc 1000mA charger to 12vdc 500mA for 12v 7Ahr battery?
You can use a resistor to reduce the current output. However, it's important to match the resistor's value to achieve the desired current output. To drop the current from 1000mA to 500mA, you would need a resistor with a resistance of about 12 ohms (Ohm's Law: R = V/I). Be cautious with this approach as it may generate heat and reduce the efficiency of the charging process. It's recommended to use a proper voltage regulator or charger designed for the specific current requirements of the battery.
Can you replace 12v vdc adapter by 12v vac adapter?
No, 12 volt AC is a different from 12 volt DC. Have a second look at the 12 AC volt adapter's output label. Most adapters contain a bridge rectifier in them that makes a conversion within the adapter. An example of this is in phone chargers.
Can you replace a transformer with an input rating of 120VAC 60Hz 12W and output rating of 12vdc 500mA with one that has an input rating of 120vac 60hz 25w and an output rating of 12VDC 1A?
Yes, you can. Here's why. If a supply's output is rated at 12 volts DC (12 VDC) and 500 milliamperes (500mA), it can deliver a maximum of 500mA at the 12 volt rating. You want to use a 12VDC supply that is rated at 1A (1000mA). That means that the supply is capable of delivering up to 1A at 12VDC. Now the crux of the matter. Your device, that's the load on the supply, needs 12VDC to operate. Your replacement supply is rated at 12VDC. No problem. Your supply delivered a max of 500mA. That does NOT mean that your load, that thing you're powering up, actually uses all 500mA. Your load knows how much current it needs to draw. Your supply has to be rated for more than that. Your supply was rated at 500mA. It worked well. The supply you wish to use will deliver a max of 1A (1000mA). It will easily supply the current your load will use. Oh, and the polarity of the new supply must be the same as that of the old one. That's pretty obvious. Always be safe and consult an electronics specialist for electrical questions. There are a number of savvy folks working at consumer electrical outlets who can get you up to speed.
What type of product would a 12v Ac Adapter be used for?
A 12v AC adapter can be use to power devices that requires 12VDC and up to 500mA. It can also be use with electrical devices that require power but do not contain internal components to derive the required voltage and power from the main power.
Can you use 12VDC in New Zealand?
Almost all cars in NZ have 12VDC electrics. Most portable generators which produce 230VAC, will also have a 12VDC accessory output for battery charging, etc. There are no general reticulations of 12VDC.
How can i make a winding of a transformer of an inverter of 12vDC to 240vAc?

Can you use a 500mA 12VDC transformer on a unit that requires a 180mA 12VDC?
From your question I assume you are referring to a charging adapter for a piece of electronic equipment. I believe adapters also contain a rectifier that rectifies AC voltage to DC. The one I'm looking at at this moment does this. Your thinking is correct, in that any thing that transforms the voltage to what you need is all you need for that step. But if your adapter rectifies the voltage you will need a rectifier with your transformer.
What is the voltage at car ac compressor?
Most all are 12vdc
How many batteries are in a Voltswagen golf GTI?
One. 12VDC 54AH.
What does 12vdc power mean?
It stands for "12 volts, direct current".
How do you if you have a 12vdc or 24 deep cycle battery?
It should be marked on the battery.
