This is a question that comes up from time to time for our subject matter specialists. Today, we have the full, extensive explanation as well as the answer for everyone who is interested!
Explanation: A Rectifier is a electrical device which converts alternating current (AC) To Directional current(DC) IN Computers.
Which component of the computer converts AC to DC?
A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies.
How do you convert AC to DC?
Divide the AC voltage by the square root of 2 to find the DC voltage. Since an AC power supply sends voltage in alternating waves, DC voltage will be lower once you convert it. Write out the formula VAC/√(2) and replace VAC with the AC voltage you found with your multimeter.
Why do computers convert AC to DC?
DC is much more easy to control, accurate and easier to propagate than DC signal. If we use AC in most of electronic circuits instead of DC, It will create extra work for just handling the phase-shift between signals. It will be harder to supply them by batteries.
What is the device called that converts AC to DC?
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC) when it reverses direction. Since it straightens the direction of current, the process is called rectification.

What is the simplest rectifier?
The simplest rectifiers, called half-wave rectifiers, work by eliminating one side of the AC, thereby only allowing one direction of current to pass through. Since half of the AC power input goes unused, half-wave rectifiers produce a very inefficient conversion.
What are the different types of rectifiers?
- Single Phase & Three Phase Rectifiers.
- Half Wave & Full Wave Rectifiers.
- Bridge Rectifiers.
- Uncontrolled & Controlled Rectifiers.
Why DC is not used in home?
Direct current is not used at home because for the same value of the voltage, DC is more lethal than AC since direct current does not go through zero. Electrolytic corrosion is more an issue with direct current.
Can DC devices run on AC?
There are devices which depend on AC in some fundamental way, like a motor creating alternating magnet fields. These do not work on DC. But other devices use DC internally, but are specified to run on AC. They convert the supply current to DC as the first step.
What are the 3 types of power supply?
There are three major kinds of power supplies: unregulated (also called brute force), linear regulated, and switching. The fourth type of power supply circuit called the ripple-regulated, is a hybrid between the “brute force” and “switching” designs, and merits a subsection to itself.
Are batteries AC or DC?
All batteries use DC, not AC. Realizing AC batteries expands more flexibility, especially when combining with the Cockcroft-Walton Multiplier, [a circuit that generates DC voltage from an input of alternating current].
Do capacitors convert AC to DC?
In DC systems, capacitor is used as a filter (mostly). Its most common use is converting AC to DC power supply in rectification (such as bridge rectifier). … Its value is calculated precisely and depends on the system voltage and the demand load current.
Can a transistor converts DC to AC?
The answer is “NO”. Transistors by themselves don’t convert DC to AC. It is not the transistor’s primary function.
Does the motherboard convert AC to DC?
All computer parts (the electronic chips on the motherboard and adapters, the electronics on the drives, and the motors in the hard drive and optical drive) need DC power to operate. … Convert AC to DC. Provide DC voltage to the motherboard, adapters, and peripheral devices.
What is secondary memory also known as?
Secondary memory is also termed as external memory and refers to the various storage media on which a computer can store data and programs.
Which is better AC or DC?
Alternating current is cheaper to generate and has fewer energy losses than direct current when transmitting electricity over long distances. Although for very long distances (more than 1000 km), direct current can often be better.
Can I use a DC adapter instead of AC?
Each AC/DC power adapter is specifically designed to accept a certain AC input (usually the standard output from a 120 V AC outlet in your home) and convert it to a particular DC output. … The key is to match the DC output of the adapter to the DC input of your device.
What is the difference between DC current and AC current?
Alternating Current (AC) is a type of electrical current, in which the direction of the flow of electrons switches back and forth at regular intervals or cycles. … Direct current (DC) is electrical current which flows consistently in one direction.
Which is safer AC or DC?
Also, the AC current can have a direct impact on our heart. … Therefore, AC current is more dangerous than DC current because it has a greater magnitude than its RMS value; it directly affects our heart as the frequency of AC current interferes with the frequency of the electric pulses of the heart.
Do we use AC or DC current in homes?
When you plug things into the outlet in your house, you don’t get DC. Household outlets are AC – Alternating Current. This current has a frequency of 60 Hz and would look something like this (if you plotted current as a function of time).
How much current is used in homes?
Most homes require an electrical service of at least 100 amps. This is also the minimum panel amperage required by the National Electrical Code (NEC). A 100-amp service panel will typically provide enough power for a medium-sized home that includes several 240-volt appliances and central air-conditioning.
What is ripple factor?
Ripple factor: Ripple factor is a measure of effectiveness of a rectifier circuit. It is defined as the ratio of RMS value of the AC component (ripple component) Irrms in the output waveform to the DC component VDC in the output waveform.
Where do we use rectifiers?
The primary application of rectifiers is to derive DC power from an AC supply (AC to DC converter). Rectifiers are used inside the power supplies of virtually all electronic equipment. AC/DC power supplies may be broadly divided into linear power supplies and switched-mode power supplies.
