在Zl=Z2的条件下,两相短路电流与同一点三相短路电流之比值为( )。
metal.(heading) Chemical elements or alloys, and the mines where their ores come from. Any of a number of chemical elements in the periodic table that form a metallic bond with other metal atoms; generally shiny, somewhat malleable and hard, often a conductor of heat and electricity. ...
Bond energy is the amount of energy that is required to separate the chemical bonds between atoms. The study of bond energy...
See also the page aboutElements Mixtures and Compounds, and Atoms and Molecules. Different Types of Mixtures: There are many different types ofmixtures, some of which have special names. These include: Homogeneous Mixtures- the (two or more) substances that form the mixture are evenly distributed...
What are examples of a metallic lattice? Metalic Lattice: A metallic lattice is an arrangement of ions where a core of cations (positively charged ions) is surrounded by delocalized, freely moving valence electrons (outer shell electrons), known as a sea of electrons. This free movement contribu...
Carbon in the form of graphite is the only non-metallic element that conducts electricity.As we all know, graphite is composed of sheets of hexagons of carbon atoms joined by covalent bonds. Between each sheet, there are weaker (pi) bonds along which the electrons are free to move. It ...
The basic requirement is that the material should not be a very good conductor of electricity, nor should it be a very bad conductor of electricity. Its properties can be changed by adding or removing atoms / impurities.Semiconductor materials include – Silicon, antimony, arsenic, boron, carbon...
