An 80-gallon electric water heater is energized for the first time. Approximately how many hours would it take to raise the water temperature 80F (26.67C) (from 40F to 120F [4.44C to 48.89C])? The water heater has a 3000-watt heating element.
Alfredo deDarke sleeps with a 7.5-Watt night light bulb on. He turns it on before getting in bed and turns it off 8 hours later. Determine the amount of energy used during one evening in units of kiloWatt•hours. Electrical energy costs 9.7027 pesos per kh-hr where Alfredo lives. Determine the annual (365 days) cost of this practice of using a 7.5-Watt night light. Determine the annual savings if Alfredo replaced his 7.5-Watt incandescent night light by a 0.5-Watt LED night light.
The total power absorbed by a group of resistors is always equal to the power absorbed by its equivalent resistance. Choose the correct answer: A. True B. False
True or false: sources of electrical energy contribute zero emissions and have no waste products associated with them. Question 8 options: True False
Voltage Drop! Assume that you were tasked to install a microwave oven using 12 AWG copper. When you look at the spec plate for the oven, you discover that the oven is rated for 240V, 60HZ, and takes a current of 25A. The location for the oven is 785.7 Ft, away from the breaker panel. Calculate the expected VD if any. Assume temperature to be 75 ̊ C. what is the Voltage Drop ? Answer?
Calculate the weight and height required for a gravity light for home use. Assume the bulb wattage is 3W and bulb has to light continuously for one hour. Take dynamo efficiency as 85% (Gravity Light is a gravity-powered lamp designed to use in developing or third-world nations, as a replacement for kerosene lamps. It uses a bag filled with rocks or earth, attached to a cord, which slowly descends and rotates the dynamo and produces the electricity for illuminating bulb). If above energy storage system is replaced with spring or spring bank, decide the required spring stiffness and the spring compression required.
A garden hose is used to fill the pool. Water comes out of the hose at a rate of 10.5 gallons per minute. How much time, to the nearest hour, will it take to fill the pool 6 inches from the top? [1 ft3 = 7.48 gallons]
Depending on voltmeter/ammeter terminal connection to the components, you might find different signed voltage and currents values for the same component. This causes different signed power values for the same components therefore we cannot state whether components generate or absorb power. What is your solution to this chaos? **please type it using keyboard NOT handwriting**
For the electric circuit shown above, the law of conservation of power requires that the algebraic sum of power for the entire circuit is equal to zero. Another way to state this is that the sum of the power generated must equal to the sum of the power that is absorbed. Use Passive Sign Convention to determine the power (in Watts) that is either delivered to or supplied by device 3. Note: The answer is a numeric answer in Watts. Make sure you have the right sign.
A university campus has 200 classrooms and 400 offices. In each classroom, there are 12 fluorescent tubes that use 110 W of electrical power per fluorescent tube. On average, the offices have half the number of fluorescent tubes. The university is open 240 days a year. The classrooms and offices are not used for 4 hours each24 hours a day, but the lights are on all day. Electricity costs $0.14/kWh.How much does the university save each year if all the lights are turned off for the 4 hours neitherclassrooms or offices are used?
Four cubic meters of water is to be heated by means of four 1.5kw, 230V immersion heating elements. Assuming the efficiency of the heater as 90%, determine the time required to boil the water if the initial temperature is 20 degree celcius and if all elements are connected in parallel.
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?
