Any device that uses 75 watts will use 75 watt hours of electricity in one hour.
In 12 minutes, 1/5th of an hour, it will use 75/5 or 15 watt hours of electricity.
This is the same as .015 kilowatt hours of electricity.

What is a laptop battery?
Laptop Battery can be any device that stores energy for later use. The word battery is limited to an electrochemical device that converts chemical energy into electricity, by use of a galvanic cell. A galvanic cell is a fairly simple device consisting of two electrodes (an anode and a cathode) and an electrolyte solution. Batteries consist of one or more galvanic cells. A Laptop Battery is an electrical storage device. Latop Batteries do not make electricity, they store it. As chemicals in the battery change, electrical energy is stored or released. In rechargeable batteries this process can be repeated many times. For more info, please click below link: www.batteriesstore.co.uk
Why does your lap feel warm when your laptop sits on it?
The heat energy dissipated by the computer. Electrical energy stored in the battery is turned into heat energy during the processes involved in running the computer. Prolonged periods of use can cause permanent heat 'staining' in the skin, as well as temporary sterility in men.
What are energy be classified into two broad groups?
This is untrue. There are 8 types of energy: 1- Light Energy- A light bulb. 2- Sound Energy- Some speakers 3- Electrical Energy- A laptop 4- Thermal/Heat Energy- A hot saucepan 5- Kinetic Energy- A moving object 6- Chemical Energy- Contained in our muscles, and contained in food. 7- Gravitation Potential Energy-The higher up. The bigger Gravitational Potential. 8- Elastic/Strain Energy- A catapult/ or elastic band. Hope this helps. Kind Regards.
How many watts are in a laptop?
There are no 'watts' in a laptop. A laptop, or any other electrical device uses electricity, and Watts measure the rate at which energy is used. Asking how many watts a laptop uses is like asking how many watts a light bulb uses. There are light bulbs that use a small fraction of a watt to those that use more than 1000 watts. As Watts measure energy consumption, it does not necessarily mean electricity: A person having a mass of 100 kilograms who climbs a 3-meter-high ladder in 5 seconds is doing work at a rate of about 600 watts. It depends on the laptop as to how many watts it uses. In electrical terms, one watt is the rate at which work is done when one ampere of current flows through an electrical potential difference of one volt. When W=Watts; V=Volts; I=Amps; R=resistance in Ohms, then W = VI or W = I2R or E2/R I have a netbook that uses a 19 volt, 1.5amp power supply. As Watts = Volts x Amps, it would appear that it uses 19 x 1.5 or 28½ watts. But that is only the power supply rating, The maximum the netbook uses is probably closer to half of that. The power supply is most likely very overrated. It operates nicely with the power supply when the battery is exhausted and being charged at the same time as being used.

This laptop has a 1.83 GHz Core Duo processor, 1 GB of DDR RAM, an 80 GB hard drive, a 14 inch screen, and wireless a/g and Bluetooth built in. It comes with the Windows XP operating system.
What kind of energy does a laptop use?
Electrical and mechanical
What is the Energy transformations of a laptop?
electrical, from charging it, sound energy from speakers, mechanical energy from keyboard and mouse, thermal from when the laptop heats up or overheats, electromagnetic/light energy from the screen/moniter
What is electrical energy used in?
Electrical Energy is used in many objects. For example the laptop I'm typing on is using a type of energy. Can you guess what it is. Well you guessed it is Electrical Energy. Here's for a better understanding -lamps, TV, computers, radios, ipods, itouches..... the list goes on and on.
How is energy lost in a laptop?
Most energy is lost through Heat, Light & Sound. Energy will also be lost through kinetic energy, that runs the fans to get the heat out of the laptop. Energy will also be used as Electrical energy to power the components, which in turn, give out heat energy. The pattern goes a little like this: Components: Electrical Energy>Heat Energy>Kinetic Energy Screen: Light Energy>Heat Energy Speakers: Sound Energy
Where can you take your laptop to get a new operating system?
you can get a new operating system online.
What exactly is a windows laptop computer?
Windows laptop computer refers to the operating system in the computer. This operating system is where your virtual memory, task, and files are stored.
What energy is changed to another energy for a computer?
Well for a start, obviously the energy starts as electrical energy. If you are running a laptop then the electrical energy will be changed to chemical energy in the battery (Li-Ion). From there the chemical energy is changed back into electrical energy though the wires and the into multiple energies such as:Light energy for the screen/monitormechanical energy and kinetic energy for the hard disk (and then into frictional)Any data traveling through cables like to the Internet is electrical energy as the computer interprets different currents from he cable back into dataAlso if you are using a mouse then that will be light/lazor energy that is scanned back into the computer. If you are using a touch pad then it is frictional.An remember that IMMA FIRIN MA LAZOR!!!!!!!!!
