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).
Measuring electrical amps is the measurement of current draw or amps or amount of electricity being consumed is an actual instantaneous measurement of actual electrical power use at the moment, not a measurement of the design capacity or capability of the electrical service at a building or in an electrical circuit.
