is this an espresso maker for a car?
if so its a pretty large heating element and will need 12v at about 30A
it doesnt matter if its dc or ac to power the heater
the ac espresso makers are around 1000w and will make more faster
heating appliances need lots of power and dont care about ac or dc
its easier to get one in the correct voltage

What is the name of the Device to convert ac to dc current?

How does auto transformer work with DC supply?
Transformers don't work with DC supplies - they only work on AC.
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
Why do you still use both ac and DC?
Because some appliances work with ac current and some with dc current.
Why electronic component work in dc and not work in ac?
That would depend on the specific component.
Can you use an AC adaptor - 3v dc 800 ma to replace AC adaptor - 9 v DC 250 ma?
no, must be 3v
Have a Universal ac dc adaptor and want to use it on a devise that says DC 10 Volt What do you choose on the adaptor it has 7 9 or 12?
Use the 9 volt setting.

Can DC series motor work on ac and DC and why?
A dc series motor can work on dc and ac because dc motors are totally reversible.
How do you install an ac power source into a digital camcorder?
Digital camcorders either work on battery or on AC power adaptor supplied with the camcorder. The DC output connector of the AC adaptor will connect to DC power input socket on the camcorder body. The location of this socket will depend on the make and model of the camcorder. Some times this socket is covered by a rubber cap which needs to be pulled out before you connect the power. - Neeraj Sharma
Can a 12V ac bulb be used with 12V dc adapter or 12v DC supply?
Answer 1: No. Answer 2: This depends. The chances are that an AC adaptor can be substituted by a DC adaptor. It depends on what item it is powering. Not many items run directly on AC power. Most items that is shipped with an AC adaptor has got its own internal rectifier in order to make DC from AC. If you know enough about electricity and electronics to open up and check the item you need to power up, then check if it contain an internal rectifier. If it does, then it should be no problem. Some times however, the diodes used for rectifying the voltage are tightly dimensioned. 4 diodes is needed to rectify the power. 4 diodes of 500ma give you a usable current of about 1 Ampere if run with an AC power-source. If using a DC power-source however, the usable current is halved because only 2 of the 4 diodes will be used. Some items that use an AC adaptor is some clock-radios or answer-machines with time-telling. For these items it is likely that they will run fine on an DC adaptor except for the clock. In Europe, the AC is 50 Hz. In US, this frequency's is 60 Hz. This frequency is highly accurate and can be used to measure time for a clock. If using DC, then the clock will not function, but the rest should. Another issue is voltage... 12 v AC... when rectified and not stabilized, it will make about 16.8 volt. When powering some item, the voltage will drop, but always stay above 12 volt. Probably more like 14 volt. This depending on current drawn. If using a 12 v DC power-source, this will after diodes only give about 11.3 volt. It may still be enough for most appliances though. If not sure about what I am writing about, then you should find a perfect match AC adaptor to your "thing" and not even test a DC adaptor on it. IF the question was reverted. "Can I substitute a DC adaptor with an AC adaptor" then in 99.9% of cases this is a big NO. If putting AC where you should put DC, this will most likely lead to destruction of your item. You will "shortcut" capacitors and transistors. It may also cause fire.
How does DC to ac power supply work?
If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC
Do laptop work on ac or DC and how?
A laptop runs on DC. Either from the battery, or the external power supply, which converts AC power to DC.
Can a dc motor work in ac?
No it cant

What instrument measures both ac and DC?
hot wire ammmeter or a moving iron ammeter will work for ac and dc.
