What is power supply short answer?
A power supply is an electrical device that supplies electric power to an electrical load. The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load.
What exactly is a power supply?
A Power Supply Unit (PSU) is an internal IT hardware component. Specifically, a power supply converts the alternating high voltage current (AC) into direct current (DC), and they also regulate the DC output voltage to the fine tolerances required for modern computing components.
What is a power supply in science?
20.1 Introduction. Power supplies are used in most electric equipment. By definition, a power supply is a device that converts the output from an ac power line to a steady dc output or multiple outputs. The ac voltage is first rectified to provide a pulsating dc and then filtered to produce a smooth voltage.
What is power supply and how do it works?
A power supply takes the AC from the wall outlet, converts it to unregulated DC, and reduces the voltage using an input power transformer, typically stepping it down to the voltage required by the load. For safety reasons, the transformer also separates the output power supply from the mains input.
What is a power supply ks3?
The power supply unit in a computer converts the powerfrom the wall outlet to the type of power needed by the computer. It sends power through the cables to the motherboard and other components.
How does power supply work?
What do power supplies do?
What is a power supply used for?
Electrical outlets deliver alternating current, or AC, power. Most electrical devices require direct current to function. A power supply converts the AC power into DC. During this conversion, the output may waver, occasionally requiring regulation.
What is power supply unit in ICT?
Power Supply Unit (PSU) There is a PSU inside every computer that provides its power. A mains powered PSU has a cooling fan at the back and a mains socket for the power cable to go into. It normally has an On/Off switch. PSU are described by their power level. For example a typical computer PSU might be 400 Watts.
What are the parts of power supply?
Parts of a Power supply Transformer − An input transformer for the stepping down of the 230v AC power supply. Rectifier − A Rectifier circuit to convert the AC components present in the signal to DC components. Smoothing − A filtering circuit to smoothen the variations present in the rectified output.
What does a power supply do in a circuit?
The purpose of a power supply is to provide power for an electronic circuit. For a given amount of power, there’s an inverse relationship between voltage and current. Whenever current increases, voltage must decrease, and whenever current decreases, voltage must increase.
What is a power supply circuit?
Power Supply Circuit. A power supply circuit is the way in which the components used in a power supply are connected and function together. The power supply circuit typically includes one or more transformers, rectifier diodes, capacitors, resistors, transistors and integrated circuits, together with a fuse or circuit breaker…
