A visco-elastic material is one with both the properties of a liquid and the properties of an elastic solid. The combination of these two types of properties is excellent when it comes to absorbing or spreading energy because these two types of materials deal with energy in different ways.
Electric and magnetic fields (EMF) are invisible lines of force that surround any electrical device. Electrical wiring, electrical equipment and power lines all produce electric and magnetic fields. Electrical fields and magnetic fields can be characterized by their wavelength, frequency and amplitude (strength).
Electrical meters measure the amount of power a building uses in a unit called Kilowatt-hours (kWh.) Electrical power is measured in watts.Electrical appliances are rated by how fast they use electricity in a unit called watts.lectrical meters measure the amount of power a building uses in a unit called Kilowatt-hours (kWh.)
