You are working as an electrician in a large steel manufacturing plant, and you are in the process of doing preventive maintenance on a large DC generator. You have megged both the series and shunt field windings and found that each has over 10 M to ground. Your ohmmeter, however, indicates a resistance of 1.5 across terminals S1andS2. The ohmmeter indicates a resistance of 225 between terminals F1andF2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer.
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?
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
