A computer's power supply converts mains AC to low-voltage regulated DC power for the internal components of a computer. You are building a new computer. You are deciding which type of power supply to install.
Which of the following definitions BEST describes a valid type of power supply?
Correct Answer:
A single-rail power supply provides one rail (PCB trace). This provides the best safety for the computer by providing a single point of shutdown in the event of a short circuit.
Correct Answer:
A single-rail power supply provides one rail (PCB trace) used to always provide equal wattage to all devices attached to the power supply.
Correct Answer:
A dual-rail power supply provides separate rails (PCB traces) used to provide equal wattage to the devices attached to each rail.
Correct Answer:
A dual-rail power supply provides separate rails (PCB traces) used to balance the power load between multiple circuits, which prevents any one circuit from becoming overloaded.
In the generation of electricity, generating too little electricity will cause __________ and generating too much electricity will cause__________________
a. Blackout and brownout
b. Brownout and blackout
c. Lights on and lights out
d. Lights out and lights on
