The avocation cut through exit discuss how a ain computing device (PC) power offer works and how a portable mp3 medication player (i.e. an iPod) power supply works. The early section of this cover up will detail how the power supplied to your PC is converted from an alternate(a) current (AC) to a direct current (DC), which is need by the individual components in the computer. The second part of this report will discuss how an iPod battery works. 2.0 PC Power Supply 2 .1 Principle Operation The power supply in a PC is typically located at the back and is overt by a power cable 3-pin connector and a engine cooling system fan. [1] Connecting your PC to the mains supply in your house will deliver an AC current to the power supply unit.

Within the power supply unit the AC input will be converted to lower DC voltages by way of Switcher Technology. Typical voltages used indoors a PC are 3.3, 5 volts and 12 volts. Generally, the digital circuits require 3.3 and 5 volts. The components within a PC needing more(prenominal) power are the disk drives and cooling fans, which require 12 vol ts. In addition, PC power supplies in an! y contingency have a circuit called VSB (standby voltage). This circuit allows the computers ON button, when pressed, to record hop out a signal to the power supply to rhythm the machine on, even when it appears to be off. 2.1.1 AC Input shelve 1 lists AC input voltage and frequency requirements for round-the-clock operation. The power supply is capable of...If you want to get a full essay, prescribe it on our website: BestEssayCheap.com
