Question

You are trying to troubleshoot a desktop power supply issue using a voltmeter. Which of the following options are the MOST common voltages produced by the power supply? (Select TWO). (Select all that apply.) (A) +/- 5v (B) +/- 12v (C) +/- 16v (D) +/- 24v

Answer 1

The correct answers are: (A) +/- 5V and (B) +/- 12V

Step-by-step explanation:

First at all, the purpose of the power supply is transforming from AC (Alternating Current) to DC (Direct Current) for use this energy in chips and electronics devices that consume this type of power. Usually the most common DC voltage for electronics is 5V but in your CPU you also have other devices that might going to need more voltage like fan or hard drives thats ´s why 12V is an also an option. Now some other devices are going to need negative sources such -5V or -12V as well.
