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

Transformers don't work with DC supplies - they only work on AC.
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.
Because some appliances work with ac current and some with dc current.
That would depend on the specific component.
no, must be 3v
Use the 9 volt setting.

A dc series motor can work on dc and ac because dc motors are totally reversible.
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
Yes, a 12V AC bulb can be used with a 12V DC adapter or 12V DC power supply. However, the bulb may not operate at its full brightness or efficiency due to the differences in the waveforms of AC and DC power. It is recommended to use a bulb specifically designed for DC operation for optimal performance.
If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC
A laptop runs on DC. Either from the battery, or the external power supply, which converts AC power to DC.
No it cant
