A power adapter Typically is an item that converts a 120VAC power signal into a much safer and lower DC signal that can range anywhere from 2 volts to 30 volts. Inside its guts, There is most likely a transformer, resistors, rectifiers, and Chips that control the current.
In case you do not understand,let me break it down:
120VAC enters into the adapter.
it enters into a step-down transformer.
this lower current enters a series of rectifiers that convert AC current into a safer and cleaner DC current.
This DC current enters a few resistors along the way.
Finally, this Much lower, cleaner, and safer current is transported out some wiring and to your laptop or other portable electronic.

What is the advantage of using a switching power supply over linear power supply?
A: Assuming the same power output the switching type will be lighter in weight and less bulky.
Why cmos consume low static power?
CMOS is a dynamic power consumer...whereas BJT consumes power always.... cmos consumes power only while switching from one astate to another state...i.e while switching
Can a 100 mA adapter be substituted with a 200 mA adapter?
A 9V 1A adapter will supply up to 9 Watts of power and a 9V 200mA adapter delivers up to 1.8W of power. The 200mA adaptor may not be able to supply enough power to a device that has been supplied with a 1A adapter. The 1A adaptor should operate equipment that originally used a 200mA adapter. Before using a different power supply, check that the outputs are both DC or both AC. If they are both DC, it is important to check that the polarity at the connector is the same for both. If AC and DC supplies are swapped or the polarity is swapped there is a risk that the equipment will be damaged.

Is there a component in the system unit that converts the wall outlet AC power into DC power?
In a wall adapter there is a device that converts AC to DC. Inside the adapter there is usually a transformer that reduces the voltage down to a working voltage of the equipment that the adapter plugs into. The output of the transformer is then connected to either a half wave or full wave bridge rectifier. More expensive adapters will have a resistive capacitive network in them to smooth out the ripple DC that is supplied on the output of the bridge rectifier.
Do you need to use a power adapter as well as a plug adapter in Egypt from the UK?
Yes! you need to use a power adapter as well a plug adapter in Egypt from the UK.
What is the use of a power adapter?
A power adapter (sometimes also referred to as a power supply) is used to supply power to a range of devices. The power is taking from the mains electricity and transferred using the adapter to the device, such as a laptop.
How does 12v dc 1.5 amp power adapter differ from 12v dc 3 amp power adapter?
12v 1.5amp power adapter is 18 Watt, can't load more than 18W power consumption,3amp power adapter can load 36W.
Can an iPod nano power adapter be used for a kindle?
Yes, the power adapter is compatible with the Kindle
What would happen if you used a 19V 3.16Amp power adapter on something that called for a 12V 3Amp power adapter power supply?
You would overload and damage the device and/or the adapter.
When plug in power adapter into power outlet no power any suggestions?
You may have blown the circuit. Does the circuit work before you connect the adapter? If so perhaps the adapter is faulty.
