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.

Explain briefly about the the circuit diagram and explanation of the analysis of equations.

Suppose the current in this circuit is I = -35 A. The voltage drop across each circuit element is as given in the table below. From this information, determine, for each of these circuit elements, (i) whether an active or passive sign convention is being used for that element, (ii) whether that element is absorbing or producing a net (positive) amount of electrical power. In each answer box within the table below, type the correct choice from among the bold-faced words above. - A A B C A + с B + V₂ Circuit element Voltage drop Sign convention? Absorbing or producing net electrical power? -5 V -6 V 1 V -

Four electricians are discussing wiring under raised floors in information technology equipment rooms. Electrician A says that wiring under the raised floor requires fire-resistant walls, floors, and ceilings between other occupancies. Electrician B says that wiring under the raised floor requires fire resistant halfway up the walls and floors between other occupancies. Electrician C says that the room must employ a disconnecting means that removes half of the power to all equipment in the room. Electrician D says that a disconnecting means isn't necessary for the room. Which of the following statements is correct? A. Electrician B is correct. B. Electrician D is correct. C. Electrician A is correct. D. Electrician C is correct.
