Electricity is a form of energy used in everyday life to power appliances, light homes, provide essential services and more.
Before electricity was widely available, people relied on whale oil lamps or kerosene stoves to illuminate their environments and ice boxes to store cold food for cooling needs. Today, our everyday lives are built around this basic commodity. This makes it essential for consumers to understand.
It is a form of energy
Electricity is an energy form manifesting itself in the movement of electrons.
Electrons are subatomic particles with either positive or negative electrical charges, and when moving they create electromagnetic fields which emit radiation such as light or radio waves.
Electricity travels through metal conductive materials as electromagnetic waves travel along their paths. Electricity also transmits audio or video signals. Understanding different forms of energy such as electricity is vital because its conversion into mechanical and heat energy forms is possible.
Energy comes from the Greek word energeia, meaning “activity.” Energy can be transferred between objects and used for work; stored within physical systems; or transformed into other forms. Furthermore, energy remains constant – it is neither created nor destroyed over time.
All matter on Earth is composed of atoms. Every atom contains protons and neutrons in its nucleus, while its outer shell contains electrons and protons, giving rise to both positive and negative charges depending on its electrical properties. An ideal state for an atom has equal numbers of protons and electrons.
An unstable atom caused by an imbalance between positive and negative charges is subject to what’s known as the photoelectric effect, where its electrons move away from its nucleus and move in random directions – this process is used in solar cells and other electrical devices that convert light to electricity.

Electricity can be created using various sources, but fossil fuels or nuclear energy is by far the most popular choice for producing it. Once produced, its energy can either be stored as potential in chemical batteries or transformed into usable mechanical or electrical energy using generators.
Current electricity requires a circuit, or closed loop of conductive wire that never ends. A circuit contains power sources to supply voltage and current as well as resistors that offer resistance against electron flow. Current is measured in amperes (A).
It is a substance
Electricity is an intrinsic property of matter that manifests in different forms. An integral component of nature, we humans use electricity for many tasks in daily life.
Electricity’s discovery and development were accomplished through scientific and engineering efforts of many notable scientists such as Benjamin Franklin, Thomas Edison and Nikola Tesla – each making significant contributions in this field.
Electric energy comes from both fossil fuels and renewable sources, including fossils such as coal or natural gas as well as renewable sources like wind or solar power.
Nuclear power is the most prevalent form of renewable energy production; other popular options are wind, sunlight and hydropower generation. Electricity can also be produced through burning coal, oil or natural gas – although using renewable sources like wind or solar power is more cost-efficient in producing electricity.
Renewable energy technologies are now widely available on the market, from wind to solar to biomass and geothermal.
All offer cost competitive power generation with various output profiles ranging from baseload to peaking, helping balance supply and demand of electricity as well as providing long term hedge against inflation.
Diversifying portfolios of renewable facilities also reduce dependence on any one form of technology or fuel imports while mitigating balance-of-payment issues associated with fossil fuel imports as well as vulnerability to price rises in energy products.
Most renewable projects have considerable local economic benefits. Construction of a project creates jobs in remote or rural locations where these installations are situated; tax revenue increases and they may even stimulate innovative business models and applications utilizing local resources like biomass.
Quality and quantity of resources are of utmost importance; temperature determines production equipment needed in geothermal energy, for instance.
Hydroelectric facilities are inextricably linked with surface water rights – potable, irrigation, navigation and recreational – requiring individual treatment due to historical complications.
Furthermore, renewables often have large upfront capital investments which require project financing; in these instances government policies that organize and streamline local institutional processes may help minimize unexpected costs or delays from adding burdensome costs onto these investments.
Electricity comes from two Greek words – electron and static, which together describe an object with static charge.
At rest, a charged particle has potential energy, which describes how much stored energy it can store. This energy can be converted to kinetic energy that can do work; its direction can be determined by measuring distance between charged objects. The farther apart their charges are, the stronger their mutual attraction forces are.
It is a property of matter
Electricity refers to a set of physical phenomena involving stationary or moving electric charges.
Charges are an intrinsic property of matter and carried by elementary particles known as electrons; accumulation or motion of these electrons produces many phenomena related to electricity such as lightning and electric heating.
Electricity has close ties to magnetism and forms part of the larger field known as electromagnetism.
Electricity is one of the primary forms of energy available to us and widely utilized. It powers electronic devices, communication tools and work equipment while also producing electromagnetic waves from microwave ovens and X-ray machines.
Like other forms of energy, electrical energy does not take the form of chemical bonds or molecules but instead arises through accumulation of excess charge on non-conductive surfaces, leading to its storage as static charge or current flow.
It comes in both static and current form. You can click the link to learn more about hva er strøm – bestestrøm which is important, for electricity consumers to learn. Static electricity results from the accumulation of charges that are unequal on objects separated by insulators, until two groups find a path between themselves to balance out their differences and create static electricity – like the kind that you can feel when rubbing a balloon against your hair.
It is this phenomenon which gives rise to static electricity.
To a person looking inside an atom, it would appear as an invisible cluster of balls enclosed within giant invisible bubbles or shells. At its center sits protons which possess positive electrical charges while electrons have negative ones – their opposite charges attract each other and contribute towards creating electric potential at each location on earth.
When an electric field is applied to a charge, its electrostatic potential transforms to kinetic energy which can then be transferred between charges for work purposes or simply used by them themselves as in the case of lightning bolts. This kinetic energy is what powers cars and other machines as well as giving lightning its lightning-like speed; its rate of movement is known as voltage.
It is a force
Electricity is a force that moves material particles. It can also produce electromagnetic waves that move materials, alter their shapes, cause vibrating sounds to occur and can even transmit information – this happens in microwave ovens and X-ray machines as well as when you rub a balloon against your hair!
Electricity powers motors and lights throughout our homes, cars, trucks, airplanes and satellites as well.
All electrical energy derives from atoms, the building blocks of our universe. Millions of atoms could fit on a pinhead and constitute every part of matter including humans and Earth itself.
Atoms tend to attract each other when close together; when far apart they repel. The forces which keep these forces in balance are called electrostatic fields. If a negative charge comes into contact with a positive one nearby, it will repel it; but by moving further away it will gain additional potential energy, measured as “volts”.
Studies of these interactions are known as electrostatics. Utilizing mathematical techniques from this field, electrostatics allows us to predict distributions of electric fields in any given configuration of charges and conductors – these predictions form the basis for transmission and generation of electricity.
Commercial buildings utilize most of the energy generated through electricity generation for five purposes, namely computers and office equipment, space cooling, lighting, and ventilation – these uses make up most of annual commercial sector electricity use.
Industrial manufacturing also utilizes electricity for process heat generation while some even generate some themselves using combined heat and power systems.
