Neither.
AC is alternating current
DC is direct current
Either can be large or small
The transmission losses are greater for (non superconducting) DC power so in most applications the absolute value of DC current will usually be lower than those in AC systems.

∙ 14y agoA typical household television is plugged into the 120V single phase AC circuit.
An AC transformer steps the voltage down to a usable level. An AC to DC rectifier produces a DC current that the tv's control electronics can use.

∙ 10y agoMost appliances run on AC which is why you can just plug them into the wall, which delivers AC, but for those which require DC, they come with a transformer which you plug into the wall (or power bar as the case may be) so that the AC can be transformed into DC.

Can you use ac dc adapter of 12 volts and 2 amps for an appliance rated for 7.5 volts and 1.8 amps?
To use an adapter of this sort, its rated voltage must match the rated voltage of the appliance, and its rated current must exceed that of the appliance. So, in your example, the rated voltage is too high to be used with your appliance.
How do you power a 1500 watt AC appliance in a car?
You can buy an "inverter." It plugs into the cigarette lighter or accessory plug or directly clips to the battery terminals and converts the 12 volt DC to AC. You can then plug your appliance into it. Be sure to get an inverter that is the right wattage capacity for your device.
Why do electrical appliance work on ac current an not in dc?
Mainly because your home is supplied with a.c. not d.c. Even those appliances (audio systems, etc.) that require d.c. supplies can be connected to an a.c. supply, because they have internal transformers/rectifiers which change the a.c. voltage to the required d.c. voltage.
How does an AC adaptor function?
To convert AC to DC, first the AC goes into a rectifier circuit, which can be as simple as a diode (which allows current to flow in one direction), or a network of diodes. The out put of this will be an oscillating from 0 to some positive voltage. Then a capacitor/resistor network which smooths out the ripple current. But before all of this happens, usually the AC goes into a step-down transformer, which will get the voltage input to the rectifier circuit in the range of the desired output DC voltage.
The only appliance allowed to be installed in the bathroom is ___ socket outlet?
Shaver
When computing wattage when to include power factor and square root of three?
In its simplest form the equation to calculate the wattage of an electrical appliance is: Watts = voltage x current. If the appliance is in a AC supply use the Route mean square voltage (the stated AC voltage).
You observe a small plaque on an electrical appliance that reads in part 115 volts AC 60 Hz This means that the appliance?
That the appliance does not need a electrical transformer and uses the US standards for electricity off the grid.
What does an electric appliance use up in its operation?
Electrical energy.
Is an iPad an electrical appliance?
yes
Is a handphone an electrical appliance?
Yes, a hand phone can be classed as an electrical appliance.
What does the average Canadian house use in electrical hertz?
The average Canadian house uses 110-120V AC 50-60Hz electricity for small appliance outlets such as Televisions, small kitchen appliances and personal computers. Larger electrical appliances such as clothes dryers, and central Air Conditioning units may use 240V AC 50-60Hz circuits.
What determines whether a 100-w light bulb cost more to use than a 1200-w hair dryer costs to use?
The electric power used by an appliance is the rate at which the appliance converts electrical energy to other forms of energy. The electrical energy used by an appliance depends on the power of the appliance and the length of the time it is used.

Is a base board heater an electrical appliance?
Yes, an electrical base board heater can be classified as an appliance.
When you pull out the plug connected to an electrical appliance you often observe a spark to which property of the appliance is this related?
I think it is due to the resistance to the electrical appliance, the resistance offered by the electrical appliance works as a load in the circuit and when load is removed it causes sparking.
Can you use a 13v 2.77 amp ac adapter in place of a 12v 3.0 amp ac adapter?
Possibly, but not if you want to invalidate the warranty to your appliance.
What does a portable appliance tester do?
A portable appliance tester is a device used to check the safety and electrical integrity of electrical appliances. It typically performs tests such as insulation resistance, earth continuity, and polarity checks. This helps ensure that appliances are safe to use and comply with electrical safety regulations.
