Electrical continuity is when a circuit is complete and can conduct electricity. Interruptions can cause damage or fire, so proper maintenance is important. Devices such as multimeters and testers can check for continuity, but power must be removed first to avoid shock. Testing a switch in the “on” position should show a reading close to […]
Industrial electronics repair involves maintaining and repairing electronic equipment used in manufacturing. It includes diagnostics, replacement of old equipment, and may take place on-site or in a workshop. Companies may offer incentives such as free diagnosis and pick-up services. Industrial electronics repair refers to the branch of electronics repair that deals with various aspects of […]
An electric linear actuator converts electric motor motion into linear motion using screw, wheel and axle, or cam mechanisms. Different types of electric motors can be used depending on the application needs. Construction techniques can vary, with some requiring a compact design. A linear actuator is a device that generates linear motion from an energy […]
An electric chain hoist uses an electric motor to drive a series of gears that pull a chain up or down. Chain drops can be added to lift heavy objects with minimal effort. It is not recommended for horizontal traction and can be used to transport heavy objects across a building. An electric chain hoist […]
Electrical test engineers are responsible for testing and evaluating electrical systems and equipment, designing product tests, troubleshooting and improving products, overseeing installations, and keeping detailed records. They typically have a bachelor’s degree in electrical engineering and experience working with complex mechanical equipment. Conducting tests and evaluations on electrical systems and equipment is the responsibility of […]
Electrical conduit protects wiring from damage and reduces fire risk. Rigid conduit includes steel or plastic pipes, while flexible conduit is easy to bend. Couplings and fittings join lengths of conduit. Conduit protects wiring from pests and moisture, but can be difficult to install and expensive. Electrical conduit is a type of tube or pipe […]
Electric skillets are frying pans that are heated by plugging them into an outlet. They provide an even heating surface and come in various sizes and shapes. They can have temperature control, non-stick surfaces, and a “keep warm” feature. However, they should be used with caution around small children and not placed on the stovetop. […]
Electric propulsion uses electric motors to power vehicles, reducing carbon emissions and pollution. Energy can be supplied externally or stored in batteries. Electric cars, boats, trains, and submarines use this type of propulsion, with regenerative braking and solar panels as options. Electric propulsion is quieter and more efficient than traditional engines, making it ideal for […]
Electric hoists lift and lower objects vertically and can move horizontally when attached to hardware. They use an electric motor and can be hardwired or driven by a generator. Hoists can use chain or rope and are rated by weight. Some hoists are designed to move across horizontal space. They are operated with a remote […]
An electric roaster is a portable cooking device that functions like an oven, with heating elements at the bottom or sides. It is similar to a slow cooker in design and can include a removable cooking grate and lid. It can steam food and prevent browning, but can also be used to cook vegetables and […]
An electric match uses electricity to ignite a fuel element. It consists of a wire inserted into the object to be lit, with the other end outside. The bridgewire and pyrogen are the two main parts. Electric matches can light household appliances, fireworks, rockets, and more. They must be handled with care and can be […]
Electric solenoids are switches used to control mechanical processes. They consist of a copper coil that creates a magnetic field when electrical energy is applied, moving a central metal shaft. They are used in automobiles, doorbells, pinball machines, and more. Solenoids can be powered by AC or DC, and their size and power needs vary. […]
Electrical resistivity limits current flow in conductors, semiconductors, and insulators. Ohm’s law relates resistance, voltage, and current. Electrical resistivity tomography creates 3D images. Different elements have varying electrical resistivity and uses. Contaminated contacts can cause plasma and shorten relay life, so electronic switches are recommended. Electrical resistivity is the characteristic of a conductor, semiconductor, or […]
Electrical conductivity measures how well materials allow electrons to flow. Conductivity is the reciprocal of resistivity. Temperature and purity affect conductivity and resistivity. Soil electrical conductivity measures salinity and other soil properties. Impurities affect conductivity differently, with minerals increasing it. Alloys are not useful for conducting electricity. Materials that naturally contain air pockets are good […]
An electric wok is a modern version of a traditional Asian frying pan that uses electricity instead of a stove for heat. It has a built-in heating element and a non-stick coating, but some argue it cannot produce high levels of heat or be seasoned properly. As the name suggests, an electric wok is a […]
Industry analysis of the electronics sector is used to determine the financial health of the industry and the likelihood of profitability for companies and investors. Analysis techniques study the impact of customers, competitors, employees, and suppliers on the market. Understanding factors of production and identifying profit sources and revenue constraints are also important. Customers in […]
Energy harassment is when a superior exhibits discriminatory or abusive behavior towards an employee, creating an unsafe work environment. Sexual harassment is a common form of power harassment, and victims should report the behavior to human resources or consult with an attorney. Energy harassment occurs when someone in a work environment experiences some sort of […]
Electric charge is a property of matter that interacts with other charged objects. Atoms consist of protons, neutrons, and electrons, with the force of attraction between protons and electrons holding the atom together. When an atom gains or loses electrons, it becomes an ion with a net positive or negative charge. Ions can attract or […]
An electrical project manager oversees electrical projects, manages teams, creates budgets, tests electrical systems, communicates with clients and colleagues, and keeps up-to-date with industry changes. They require engineering licenses and strong leadership and interpersonal skills. An electrical project manager is an individual who oversees the development of electrical projects for clients, which includes ensuring that […]
Electric generators and motors convert mechanical energy into electrical energy and vice versa. All energy requires a resource and a device to convert it. Generators use electromagnetic induction to convert mechanical energy into electrical energy, while motors convert electrical energy into mechanical energy. Both have a rotor and stator, and are used in power plants […]
