Most electronic equipment runs on DC (direct current), while the power supplied at receptacles is AC (alternating current). Some electronic equipment contains a power supply internally that converts AC to the required DC. Other equipment requires an external adapter to convert.
When looking at an adapter it is important to get one that is compatible with the requirements of the equipment. The wrong adapter can damage equipment, or overheat. An adapter should be labeled with the following information.
1. check that the adapter input voltage matches your local power (i.e. 110-125VAC in US)
2. check that the adapter output voltage matches the equipment to be powered.
3. be sure the adapter output voltage is DC if the equipment requires DC--some adapters produce AC.
4. check that the adapter can supply at least as much current as the equipment requires. If it can supply more, that is fine. This will be in amps or more typically milliamps (mA) (for example it will say "200mA")
5. check that the connector on the adapter matches the input to the equipment-can it be plugged in?
6. important--even if the connectors mate, check that the polarity is the same. Unfortunately some commonly used power plugs are found wired both ways. For example, on round power connectors, sometimes the center is positive, sometimes it is negative.

How do you spell AC DC?
Most people think that you spell AC DC like A-C-D-C. But really, the abbreviation is spelled A-C-Lightning bolt-D-C. It's a common mistake. LOL. |{.|{. That's all.
Why ac instead of dc?
ac transmission are used because we easily step up the voltage as per our requirment and also breaker used for ac break the ac current easily bcs of nature of zero current at every cycle but for long distance transmission done by dc due to reducing the skin effect and also reduce the relative inductance of the line due to this the line losses are reduce and we transmit the more power.

Can a 9 volt 100mA ac adapter be substituted for a 9 volt DC 300mA adapter?
No. an AC adapter will not work for equipment that needs DC.
What AC actually means in AC adapter?
Alternating Current ... like in most households.The adapter is either converting DC to AC or vice versa.
Is a AC adapter the same as a charger?
An ac adapter converts ac current into dc current through a rectifier, and a battery charger outputs dc current at an adjustable powerful charging rate and also converts ac current to dc current to charge different sizes of batteries.
