A homeowner uses a 100-watt incandescent lamp as a heater in an outside well pump house to protect the pump from freezing in cold weather. Unfortunately, however the lamp can burn out and leave the pump unprotected. You have been asked to install a heater that will not burn out and leave the pump unprotected. You have available a 100-watt, 150-ohm wire-wound resistor Can this resistor be connected to the 120-volt source without damage to the resistor? If so, what would be the power output of the resistor?

You are an electrician installing the wiring in a new home. The homeowner desires that a ceiling fan with light kits be installed in five different rooms. Each fan contains a light kit that can accommodate four 60-watt lamps. Each fan motor draws a current of 1.8 amperes when operated on high speed. It is assumed that each fan can operate more than three hours at a time and therefore must be considered a continuous-duty device. The fans are to be connected to a 15-ampere circuit. Because the devices are continuous-duty, the circuit current must be limited to 80% of the continuous connected load. How many fans can be connected to a single 15-ampere circuit? How many circuits will be required to supply power to all five fans?
Basic Electrical Engineering A homeowner uses 100-watt incandescent lamps as a heater in an outside well pump house to protect the pump from freezing in cold weather. Unfortunately, however, the lamp can burn out and leave pump unprotected. You have been asked to install a hearth that will not burn out and leave the pump unprotected. You have available a 100-watt, 150-ohm wire-wound resistor. Can this resistor be connected to the 120-volt source without damage to the resistor? If so, what would be the power output of the resistor? (Hint: Use power formula)
Basic Electrical Engineering A homeowner is installing a swimming pool. You have been asked to install a circuit to operate a 600-watt underwater light and a circuiting pump. The motor nameplate reveals that the pump has a current draw of 8.5 amperes. The devices are considered a continuous duty. Can the power to operate both of these devices be supplied by a single 20-ampere circuit? The voltage source is 220 V.
A homeowner uses a 100-watt incandescent lamp as a heater in an outside well pump house to protect the pump from freezing in cold weather. Unfor- tunately, however, the lamp can burn out and leave the pump unprotected. You have been asked to install a heater that will not burn out and leave the pump un- protected. You have available a 100-watt, 150-ohm wire-wound resistor. Can this resistor be connected to the 120-volt source without damage to the resistor? If so, what would be the power output of the resistor?
A renowned wind turbine company wants to sell you a wind turbine to go on your roof. They say that you will be able to produce all of the electricity required for your home because their “WindX 5,000” turbine has reached an efficiency of 73%. Is it feasible to buy the turbine? Would you buy this turbine?
A voltmeter having sensitivity of 200 ohm/volt reads 119 V on its scale of 219 V when connected across an unknown resistance in series with a multimeter. When the multimeter rads 5mA, calculate the error due to the loading effect of voltmeter. Also calculate the error if the milliammeter reads 800mA and voltmeter reads 40V on its 219 V scale.
You have a cabin in the Colorado wilderness far away from civilization and wantto install a small hydro generator to provide electricity. A stream runs down a hill behind your cabin where you can construct a simple run-of-river hydro installation. You calculate that the effective head of the installation is 25 feet and that water would flow through the system at a rate of 50 cubic feet per minute. The simple inexpensive hydro turbo-generator (turbine mated with electric generator) that you intend to buy has a working efficiency of 60%. Answer the following (show your work):a.How much power can you generate with this system?(1.06 kW)b.How many 100 watt light bulbs can you power with this hydro setup?(10 bulbs)c.What type of turbine would you expect to find in your turbo-generator? Why?
The copper coils of a generator have an equivalent resistance of 10 Ω at 20°C. After being used for several hours, the resistance is found to be 12 Ω. Determine the temperature of the coils.
A toaster has a heating element which has a temperature coefficient of resistivity of 2.0 x 10-3 (°C)-1.The toaster is plugged into an outlet which delivers a constant voltage. If the resistance of the wire did not change with temperature, the toaster would be able to toast a piece of bread (at 22 °C) in 20 s. If the toaster reaches a temperature of 250 °C, how long does it actually take to toast the same piece of bread?
How can you explain scientifically the generation of high voltage to feed the ignition plugs in car engine about 11KV while the voltage source is a battery 12V
The copper coils of a generator have an equivalent resistance of 9.5 Ω at 20 °C. After being used for several hours, the resistance is found to be 12.2 Ω. Determine the temperature of the coils in °C.
An electric boiler has two heating elements each of 230V, 3.5kW rating and contains 8L of water at 30 deg C. Assuming 10%loss of heat from the boiler, find how long after switching on the heater circuit, will the water boil a atmospheric pressure if the two elements of the heaters are in parallel
