∙ 11y agoAny 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.

∙ 11y agoA laptop battery is a rechargeable power source that provides the necessary energy for a laptop to function without being connected to a power outlet. It is usually located within the laptop and powers the device when it is not plugged in.
Laptops generate heat during use, and when placed on your lap, the warm air from the laptop's fan circulates around it, making your lap feel warm. Additionally, the heat produced by the internal components of the laptop can transfer to the surface it's resting on, further contributing to the warmth you feel.
It is unlikely that you will get electrocuted from broken headphones connected to your laptop while it is charging. However, using damaged electrical equipment can increase the risk of electrical hazards and should be avoided. It is recommended that you replace the broken headphones with new ones to ensure your safety.
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 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.
Electrical and mechanical
A laptop takes electrical energy from the battery or power source and converts it into various forms of energy such as light (display), sound (speakers), and mechanical energy (fan). It also generates heat energy as a byproduct of its operations.
Light bulbs: Light bulbs use electrical energy to produce light. Television: Television sets use electrical energy to power the screen and speakers. Laptop computers: Laptops use electrical energy to operate the display, processor, and other components.
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.
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
