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).
Best Answer: Electricity is measured in volts, amps and watts. Volts measure the âpressureâ under which electricity flows. Amps measure the amount of electric current. Watts, named to honor the inventor of the steam engine, James Watt, measure the amount of work done by a certain amount of current under a certain pressure. One watt is a very small amount of power. On average, a typical household incandescent light bulb uses 40 to 100 watts.
