Basic Electrical Engineering You have been sent to a new home. The homeowner reports that sometimes the electric furnace trips the 240-V, 60-A circuit breaker connected to it. Upon examination, you find that the furnace contains three 5000-W heating elements designed to turn on in stages. For example, when the thermostat calls for heat, the first 5000-W unit turns on. After some period of time, the second unit will turn on, and then, after another time delay, the third unit will turn on. What do you think the problem is, and so would your recommendation for correcting? Explain your answer.

A container equipped with a resistance heater and a mixer is initially filled with 3.6 kg of saturated water vapor at 120°C. Now the heater and the mixer are turned on; the steam is compressed, and there is heat loss to the surrounding air. At the end of the process, the temperature and pressure of steam in the container are measured to be 300°C and 0.5 MPa. The net energy transfer to the steam during this process is

A typical exterior masonry wall of a house, shownin the accompanying figure, consists of the items in theaccompanying table. Assume an inside room temperature of 68F and an outside air temperature of 10F,with an exposed area of 150 ft2. Calculate the heat lossthrough the wall.
Lightbulbs are rated by their power consumption in watts (W). Electricity is sold in units of energy, which is power multiplied by time. Electricity costs vary widely across the United States and are on the order of 0.08–0.30 $/kW-hr for residential customers. Create a spreadsheet that utilizes electricity costs and the number of hours per day that a lightbulb is on as input variables. Then calculate the annual cost to operate a 60-W, 75-W, and 100-W incandescent bulb and the equivalent LED bulbs consuming 8, 10, and 16 W, respectively. Assuming the average household operates six 60-W, four 75-W, and two 100-W incandescent bulbs for 6 hours a day, how much money can they save in a year by changing all the bulbs to equivalent LED bulbs?
Why is there a need to separate some appliances in a circuit and place them in their own circuits (individual circuits)?Give illustrations to further explain your point.
A family of five is planning to install solar panels on the roof of their home to help reduce the cost of electricity and save energy to help the environment. The family plans to install 10 panels, each with a power rating 600W. On average, a solar panel can produce electricity for 4.5 hours daily. Each person in the family uses electrical energy at an average rate of 2kilowatt-hour per day. Will they still need to buy electricity from an electrical energy supplier? Explain your reasoning.
Based on Professional Morality, explain the following professional engineering scenario wherein two(2) electrical engineers are paid to prepare Electrical System Design of a high-rise mixed commercial and residential building. The first engineer's design leans towards the safety operation and maintenance of building, whereas the other engineer's design favors initial cost of the project. Provide at least three (3) instances that its more reasonable to choose a design that has favored safety over economical criteria of the design.
