Deregulation of the electricity sector has had mixed results. Advocates hope to end monopolies and lower prices, but detractors argue that demand remains fixed. Belgium and England have completely deregulated, while the rest of Europe maintains a hybrid system. The US deregulated in the 1990s, but customers in deregulated areas pay more. However, some companies […]

An electric compressor is a machine that pressurizes and stores air inside a […]
Power drills are motorized tools used to drill holes in materials such as wood, plastic, and metal. They are commonly used in construction and building, but also for household projects. They can be cordless or corded and have various speed settings and accessories such as drill bits and screwdriver sets. The motor and power supply […]
An electric planer is a portable power tool used to adjust the thickness of wood and create a flat surface. It can cause snipe, but experienced woodworkers can avoid it. Cordless models are for smaller jobs, while those with a power cord produce more even power. Some models have a dust collection system to reduce […]
Electric bells use electricity and an electromagnet to produce sound. They have been used in telephones, level crossings, factories, schools, and security devices. New technologies have replaced them in many applications, but they are still available as specialty items. An electric bell is a type of bell mechanism that works with the use of a […]
Electric grills are a safe and efficient way to grill food, with different types available for indoor and outdoor use. They are easy to use and store, and come in a range of prices. As a popular alternative to charcoal or gas grilling, the electric grill has gained a lot of attention over the past […]
Electrical insulators protect and shield conductors from electric current. They can be made of glass, porcelain, rubber, Teflon®, and silicon dioxide sleeves. Composite insulators are made of a combination of materials and are suitable for various electrical engineering purposes. Electrical insulators, also sometimes called “dielectrics,” are materials that can withstand and absorb the flow of […]
Electrical fires are caused by electric arc, poor wiring, or external heating. Water should not be used to put out an electrical fire, but dry chemicals like carbon dioxide or baking soda. Turning off the power and using a fire extinguisher is recommended. When it comes to fire, most people expect a flammable material like […]
Electrical Metal Conduit (EMT) is a lightweight, cost-effective option for enclosing electrical wires. It is made of steel or aluminum and often galvanized to resist corrosion. EMT is popular for indoor and outdoor use, easy installation, and controlling the flow of electricity. However, it may not be suitable for all applications, such as when a […]
An electric pallet truck is a motorized vehicle used to move and transport pallets in workplaces like warehouses. They are known for their easy handling and speed, and can carry loads up to 3000 lbs. Drivers may need a license or training to operate them. An electric pallet truck, sometimes referred to as an electric […]
An electric trowel is a construction machine that smooths freshly poured concrete slabs using one or two rotors with spinning discs or multi-bladed attachments. Walk-behind or ride-on models are available. A screed is used for small slabs, while power trowels are preferred for larger slabs. The trowel is a simple platform with a gasoline engine […]
Electric juicers come in different types and prices, ranging from under $100 to over this amount. They can be single-use or multipurpose, and are classified as centrifugal, masticating, or shredding. Twin gear juicers are the most expensive but the best for multipurpose use. Before buying, consider how the juicer will be used. Used juicers can […]
Electric bread slicers are kitchen tools used to slice bread quickly and evenly. They come in industrial and home sizes, with the ability to set different slice sizes and handle various foods. They are responsible for the uniformity of store-bought bread slices, and smaller bakeries often use them for professional slicing. Manual bread slicers are […]
Electrical design software allows architects and electricians to draw diagrams for building wiring and electronics, ensuring suitable materials are used and regulations are followed. It also helps manufacturers assemble small electrical components and is available in customizable options with color-coded diagrams. Electrical design software allows an electrician or electrical engineer to draw diagrams, plans, and […]
Electric shock can damage the human body by disturbing the nervous system or causing severe burns. The body’s sensitivity to electricity is due to its reliance on electrical impulses to carry information. Electric shock can also be used as medical treatment to correct problems with the nervous system or restart a heart. An electric shock […]
Electrical symbols represent components in diagrams and schematics, but there is no global standard. Some organizations have established their own guides, while others use private codes. Lack of standardization can cause confusion. Symbols provide a clear visual overview and are used in technical documentation and academic settings. An electrical symbol is a visual symbol that […]
Electrical service technicians repair electronic equipment in various settings, including homes and businesses. They may work for retail or service companies or be self-employed. They need problem-solving skills, manual dexterity, and communication skills, and may require training or certification. An electrical service technician services electronic equipment in a wide variety of settings. An individual in […]
Acoustic music is produced by instruments without electronics, while electronic music is produced and/or altered by electronic means. Electronic music emerged in the 1890s-1950s and includes both electronically synthesized sounds and musique concrète. The original equipment included dynamic suppressor, filter, and tape recorders, while synthesizers and sequencers were introduced in the 1960s. Electronic instruments include […]
An electric field is the influence of an electrically charged object on other charged bodies. The field is infinite but decreases with distance according to the inverse square law. The field’s direction and magnitude depend on the type of charge. The force experienced by a charged object in an electric field can be calculated using […]
Electronic and computer engineering share common skills in designing and understanding hardware. Both require studies in computation, programming, electronics, and electrical theory. Computer engineers focus on operating systems, networks, and software while electronic engineers deal with microprocessors and motherboard components. Both electronic and computer engineering are fields that deal with the physical hardware components of […]
