Read OnElectric and magnetic fields are invisible areas of energy (also called radiation) that are produced by electricity, which is the movement of electrons, or current, through a wire. An electric field is produced by voltage, which is the …
Read OnHAZARDOUS LOCATION CLASSIFICATION. Hazardous Locations consist of areas where there is the potential for a fire or explosion due to electrical equipment that is in operation in this area with a reaction to flammable or ignitable gases, liquids, vapors, combustible dusts, fibers or flyings. The need for Explosion-Proof equipment then arises due ...
Read Onability to create electrical current in a conductor by moving a magnetic field past the conductor. The reverse is also true: a magnetic field is produced in a conductor by passing electrical current through the conductor. In general, the requirements for electromagnetism are a magnetic field, a conductor, and relative movement between them.
Read OnIn these videos and articles the definition of electric charge will be given as well as a discussion of the law of conservation of charge. You'll learn how Coulomb's law relates the electric force to charge and separation distance. The difference between an electrically conducting vs. electrically insulating material will also be discussed.
Read OnThe electric field E at a point in space is defined to be the amount of electric force per charge exerted at that point in space. So this is what the electric field is. It's the force per charge. The way physicists …

Schematic diagram: a diagram that uses lines to represent the wires and symbols to represent components.
Read OnAn electrical isolator switch is one kind of device used to isolate a specific circuit by maintaining as well as preventing flowing currents. These switches are used in electrical appliances like kitchen tools, power grids, etc. Isolator switches are available in different types like a single-pole, double-pole, 3-pole, 4-pole, fused, and battery isolator switches.
Read On1 W/m² = 1000,000 µW/m². 1 μW/cm² = 10,000 μW/m². (We can also use cm² instead or m².) But these are all the same thing. We are measuring the effect in Watt on a specific surface area (m² / cm²). instead of looking at the difference in Volts between two points we are measuring what we call the "power flux density".

Read OnElectrical motors are an electro-mechanical device that converts electrical energy to mechanical energy. Based on the type of input we have classified it into single phase and 3 phase motors. The most common type of 3 phase motors is synchronous motors and induction motors.When three-phase electric conductors are placed in certain geometrical positions (i.e. …
