What voltages does a computer's power supply convert 120 volts of alternating current from a wall outlet into?
A personal computer's power supply receives 120 volts of AC and converts it to 3.3, 5, 12 volts of DC power.
Another answer
The secondary voltage could be any number of voltages depending on what the power supply was designed for. Your best bet is to get a DC voltmeter and measure the output voltage of each wire on the output side.

Alternating current travels in only one direction and is typre of current that most electronic devices require including computers?
True ~tekno
What does the symbol AC stand for?
If you're meaning AC as in Electricity then you're talking about Alternating Current. There are normally symbols on Electronics or Computers.
A power supply receives what type of power?
It depends on the type of power supply. A power supply used in a desktop computer is generally supplied with AC (Alternating Current) and produces several levels of regulated DC (Direct Current) voltages required by the electronic circuits.
Changing alternating current to direct current is called?
Rectification
What is AC power plug?
an AC power plug is one that utilizes AC (or alternating current) to power a device. Alternating current is different to direct current (or DC) in the way that instead of providing a direct source of power, it alternates between negative and positive. Most devices rely on Alternating current due to circuitry reasons
What is the meaning of voltages?
D.C. stands for direct current. A.C. is alternating current.
What converts direct current to alternating current?
To convert direct current to alternating current you need either an inverter or a motor-generator set.
Which device is used to convert direct current into alternating current?
An inverter
How does a device convert direct current (DC) to alternating current (AC)?
A device called an inverter is used to convert direct current (DC) to alternating current (AC). The inverter switches the direction of the current flow at a rapid rate, creating an alternating current output from the direct current input.
What is use of rectifier?
Rectifier is used to convert alternating current to direct current.
Electric current from a generating plant is?
Electric current from a generating plant is typically alternating current (AC), which flows back and forth in a rapid and regular manner. This AC current is then transmitted through power lines to homes and businesses for use in electrical appliances and devices.
Alternating currents travels in only one direction and is the type of current that most electronic devices require including computers?
It seems there is a misconception. Alternating current (AC) constantly changes direction, while direct current (DC) flows in one direction. Most electronic devices, including computers, typically require direct current for operation, but they convert AC from the mains power supply using a power adapter or internal power supply unit.
What is the purpose of a alternator?
A car alternator generates alternating current, then uses a rectifier to convert the alternating current to direct current, it charges your battery and supplies the current to run all the electrical systems in the car.
Is a device that changes the voltage of an alternating current with little loss of energy?
The device you are referring to is called a transformer. Not only can a transformer increase voltage, it can decrease voltage as well. These are known as a step up transformer for increasing voltages and step down for decreasing voltages.
Why is alternating current better than direct current for transmitting electricity over long distances?
Alternating current is better than direct current for transmitting electricity over long distances because it can be easily converted to higher or lower voltages using transformers, which reduces energy loss during transmission. Additionally, alternating current can travel longer distances with less power loss compared to direct current.
What is an example of a direct current?
A direct current (DC) is the continuous flow of electric current that circulates in one direction and keep the same polarity (positive or negative). Example of direct current are batteries and generators. There are electronic devices, like computers, that work with direct current, but they require of some additions to convert alternating current to direct current.
What type of diode is used to convert alternating current into direct current?
The type of diode used to convert alternating current in to direct current is the power diode.
