How hot can a jet engine heat air? How are jets made in particle physics? How does a solid fuel rocket engine work? How does a Van de Graaff generator create static electricity? How is an electric field created? How does an electric field produce a magnetic field?
How does a transformer work?A transformer is based on a very simple fact about electricity: when a fluctuating electric current flows through a wire, it generates a magnetic field (an invisible pattern of magnetism) or "magnetic flux" all around it. The strength of the magnetism (which has ...
How does electricity work? Why does my electricity bill fluctuate throughout the year? You likely use more electricity during certain seasons than others, especially if you live in a state with clearly defined seasons or frequent extreme weather. For example, heat waves often cause spikes in el...
How Does an Electric Meter Work? You’ve probably stared at the spinning numbers on a power meter and wondered, "What does an electric meter do, and how does it calculate my energy consumption?" The disc in an analog meter simply spins as you pull kilowatt-hours (kWhs) of electricity fr...
Heat is the most common way we see light being generated -- a normal 75-watt incandescent bulb is generating light by using electricity to create heat. Electricity runs through a tungsten filament housed inside a glass sphere. Because the filament is so thin, it offers a good bit of resista...
So how does all of this come together in your home? Let's find out. Circuit Breaker: At Work in Your Home This diagram shows the basic parts and design of a circuit breaker. HowStuffWorks The power distribution grid delivers electricity from a power plant to your house. Inside your hou...
How much does it cost to run a heat pump?(They are considered very energy-efficient) How big a generator do you need to run a heat pump?(Start-up wattage is key here; in the event of a power outage) Will a solar panel system be able to provide enough electricity to power a heat...
Learn all about electricity - how it works, where it comes from, and what the future of electrification means.
Electricity lights up our world, but where does it come from? See more nuclear power pictures. Mitchell Funk/Photographer's Choice/Getty Images Humans have an intimate relationship with electricity, to the point that it's virtually impossible to separate your life from it. Sure, you can ...
Petroleum companies are also developing alternatives in addition to more traditional forms of drilling. They includenon-hydraulic fracturingthat can penetrate rock without creating large volumes of wastewater. Renewable energies such as wind and solar power can also be used to generate electricity without...
