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).
The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.he volt is a measure of electric potential. Electrical potential is a type of potential energy, and refers to the energy that could be released if electric current is allowed to flow.
