The AC power adapter is used to power electronics of many kinds. Some popular electronics include tape recorders, VHS players, laptops, and video game consoles.

Does DC adapter mean the device converts DC to ac or ac to DC?

An AC adapter adapts the device that one wants to power up to the AC line. That means it converts the AC line voltage to something that can be used by the device in question. An AC adapter converts AC to DC. (In contrast, a device that runs off DC and makes AC out of it is called an inverter. An example of an inverter is the device that plugs into a vehicle's cigarette lighter and has an outlet on the other end that will permit someone to plug something like a kitchen blender into it. Great for tailgating! Don't run your vehicle's battery down....) There are times when an AC adapter is the little plug-in-the-wall thingie that converts the AC line voltage to some lesser value of AC. There are a few devices out there (usually older ones) that used their AC adapters to step down the wall voltage (115 volts AC) to 24 volts AC, 18 volts AC, 9 volts AC, or anything like that. Some new sprinkler control timers use an adapter that is an AC -to-AC step down converter. By looking at the information on the adapter, the user can see what the primary voltage is (and it's almost invariably 115 volts AC or 120 volts AC - same, same for this application) and what the secondary voltage is. As stated, the secondary is almost always DC, and if it is, the polarity is almost always indicated as well. That's so a user can tell if that little round connector has positive on the inside and negative on the outside or the other way round. (It makes a lot of difference to the device on which it is used, as one might guess.)


Can you run a 12 volt ac water pump with a 12 volt dc adapter?

No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.


Can an ac adapter's output be AC?

Yes an AC adaptors output can be AC. In order to change the output to AC a few components inside of the adaptor has to be removed. Pretty much all that has to be removed from the adaptor are the diodes. The gaps in the circuit then have to be bridged in order for the electricity to continue to flow to the output plug. However this can cause problems with the circuit causing the capacitors to explode. I dont recommend modifying an adaptor to output AC. Just go out and buy another one.


Why was the ac electrical generator invented?

"AC" is just a scientific term that refers to the fact that this generator produces electricity in an Alternating Current as opposed to "DC" which refers to Direct Current. Commonly, the plug outlet on the wall is AC, and the little black box electrical adapter for your cordless telephone is changing that AC current into DC current for the phone to work on. The phone line in your house runs on 24 volts DC, where the wall sockets are 124 volts AC.


Are Christmas lights ac or dc current?

Christmas light have always been AC.
