You are an electrician. You have been asked by a homeowner to install a lighted mirror in a bathroom. The mirror contains eight 40-watt lamps. Upon checking the service panel, you discover that the bathroom circuit is connected to a single 120-volt, 20-ampere circuit breaker. At present, the circuit supplies power to an electric wall heater rated at 1000 watts, a ceiling fan with a light kit, and a light fixture over the mirror. The fan motor has a full-load current draw of 3.2 amperes and the light kit contains three 60-watt lamps. The light fixture presently installed over the mirror contains four 60-watt lamps. The homeowner asked whether the present light fixture over the mirror can be replaced by the lighted mirror. Assuming all loads are continuous, can the present circuit supply the power needed to operate all the loads without overloading the circuit?

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.
