A laptop is operated for an average of three hours a day, and it remains off but connected to power the rest of the day. While it is working it demands 60W and when it is "off" it demands 3W. The cost of the electrical energy is $ 500 / kWh. How much does the energy I consume cost me per year the laptop? B) How much will I save if I disconnect it from the power when turn off ?.

Heat energy is often measured in calories and 1 calorie = 4.184 Joule. It is desired to design a heating element to boil a certain amount of water in 2 min requiring 40-kcal heat energy. If the heater is to operate at 110-V, calculate its current and power ratings.
Suppose the cost of an incandescent bulb is 28 cents and that electricity costs 10.5 cents/kWh. Compact fluorescent lightbulbs (CFL), while they are more expensive, use 1/10 of the power for the same amount of illumination. What would be the maximum cost (in dollars) of a CFL such that the total cost (investment plus operating) would be the same for both CFL and incandescent 60 W bulbs? Assume both lightbulbs run for 1000 h.
I need very QUICK answers, PLEASE. A coal-fired thermal power plant produces 1100MW of power annually with an efficiency of 44%. The annual operating rate of the plant is 70%. It is desired to establish a Solar Power Plant instead of this power plant. Calculate the required Solar Cell area since the power density of the solar cells used in the power plant to be established is 100W/m^(2).
An overhead power line travels 10km to supply a factory with 10MW of power (1MW = 1 × 106 W ). If the power line reaches the factory at 60 kV , what radius should it have so that it dissipates 1% of the power delivered (1% of 10MW)? Take the wire to be made out of copper with ρ = 1.68 × 10−8 Ω · m.
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.
A static electrical device has 2000 turns uses 4000 mA from the supply connected to a laptop whichhas a power of 20 V, 1000 W. How can you find the amount of current used by the laptop? Identify suchstatic electrical device used and evaluate supply voltage taken by it. Which category does it belong basedon its ability to change voltage? Practical efficiency of such electrical device is less than 100 %. Justifywith reasons. What are possible ways to improve its efficiency?
Assuming a global population of 9 billion people, each using approximately 100 W of power continuously throughout the day, calculate the total land area that would have to be set aside for photovoltaic power generation, assuming 800 W/m2 of incident solar power and a conversion efficiency (sunlight to electricity) of 10%. The total land area that would have to be set aside for photovoltaic power generation is km2.
5. What is the power formula when work is not given? a. What is the unit of measurements that each has to be in? b. What is the power of a 400N student walking 5 meters in 30 seconds?
(a) Calculate the power per square meter reaching Earth’s upper atmosphere from the Sun. (Take the power output of the Sun to be 4.00×1026 W.) (b) Part of this is absorbed and reflected by the atmosphere, so that a maximum of 1.30 kW/m2 reaches Earth’s surface. Calculate the area in km2 of solar energy collectors needed to replace an electric power plant that generates 750 MW if the collectors convert an average of 2.00% of the maximum power into electricity. (This small conversion efficiency is due to the devices themselves, and the fact that the sun is directly overhead only briefly.) With the same assumptions, what area would be needed to meet the United States’ energy needs (1.05×1020 J)? Australia’s energy needs (5.4×1018 J)? China’s energy needs (6.3×1019 J)? (These energy consumption values are from 2006.)

A household installs solar panels and captures more energy than it consumes. However, their peak energy use is in winter when they display holiday lights and heat their home, and their peak energy generation is in summer when they get more direct sunlight. What technology can help store energy to be used later ?
